After watching "City Lights", talk about those villains who hate and suck powder.

"Lovely and charming villain" — — Huston Rockets


Special feature of 1905 film network "In order to prevent the world from being destroyed, to protect the peace of the world, to carry out the evil of love and truth, a lovely and charming villain … …” I believe that many friends like me who are in Grade 2 are familiar with the classic and magical lines in this cartoon Poké mon. It’s not easy to really be a charming villain.It can make people (within the correct scope of the three views) gnash their teeth and feel pity, which is indispensable and impressive, and can be described as the highest realm.


 Heath Ledger’s "Clown" Image


There are very few "top-level" villains who can meet the above conditions one by one, butJoker, the clown played by Heath Ledger in the film, is undoubtedly one of them..In the years since Nolan’s Batman series was deified, both the character’s own creativity and Heath Ledger’s personal performance have been analyzed in detail countless times, and it is unnecessary to repeat them: everyone is afraid of clowns, and the endless and unreasonable crimes he brings are disgusting and chilling, but his extremely tragic life makes people willing to understand his desperate resistance to fate.

Villain Jiangya

 

At present, the villain Jiangya is a bit of a clown, but he seems to be more like a combination of a clown and Batman:Pretending to be "the light of the city", because "the city needs a beam of light", he completed the "dark trial" of the evildoers in the city in his own way (murder full of ritual sense), but he also had no scruples about involving innocent people in his own murder plan.

 

A mysterious, cautious, evil and full of "sense of justice" contradiction, which is exactly what Remy, the original author of "Psychological Crime" series, wants to describe as a "different and charming" villain in the final chapter of the first season. As a person standing on the opposite side of "justice", the stories, emotions and conflicts that the villain needs to bear and express are more complicated and intense."A good villain should have a complete set of values that belong to him. This value may be absurd, but it must be convincing and may even confuse people."Remy understands the creation of villains like this.

 

Jiangya villain image is very complicated.

From the plot of "City Light of Psychological Crime", we can see the shadow of childhood domestic violence hidden in Jiangya’s heart. This victim’s identity is not only the basis of his opponent’s worship (even distorted worship), but also gives the most reasonable motivation for his birth and action after "City Light".The real world is never simply black and white. The more three-dimensional the complexity of human nature is, the more it can touch people’s hearts."Jiang Ya incarnated’ justice’ in the middle of the night. This kind of revenge (at the first time) will make people feel very Japanese, but how should we choose when we really face the law? Such a role may arouse the audience’s relatively complicated feelings towards him. " Remy said. In other words,I’m afraid this kind of complexity is our own struggle between the correctness of the three views and the deep sympathy.


Batman confronts the clown

 

The clown and Jiang Ya also introduce another important attribute of the "charming" villain — —Only above the successful villain can we see better heroes.The clown throws a dilemma multiple-choice question, which makes Batman finally understand where the just soul is after experiencing confusion and pain. The same is true of Jiangya, who uses a series of murders to stir up the high emotions of the people and also test the bottom line of the protagonist. It was the murder of an innocent little girl that made Fang Mu determined to fight to the death with the "city light" in extreme resentment and collapse.

Andrew scott plays Professor moriarty in Sherlock.

 

Tracing back to the classics, Professor moglia in the detective novel adventures of sherlock holmes can also be called such a figure. Since the publication of the original work in the 19th century, it has been adapted into numerous versions by film and television. In the most popular BBC English drama version in recent years, actor andrew scott once again gave this deadly enemy a brand-new look with a version of moriarty, which is as crazy and magical as a clown.

 

Of course, in addition to these villains who need to build on the plot to display their "charming" charm, there is also a class of villains who are relatively simple and rude. They can easily circle the powder by eating people and setting bonuses.Ill-tempered, self-willed, anyway, stories and characters give infinite space, as long as you boldly release yourself, there will be a large number of fans willing to fall for it.


Tom Hiddleston plays the evil god Loki 3.

 

The absolute leader of this kind of villains is Loki, the evil god in the series of Raytheon by MCU. When it comes to doing bad things, he can disturb the order of the universe, destroy the heaven, piss off Dad and brush his brother around. Although it’s not bad to the bone, it’s still an absolute TOP in the jerk index. As for PK’s popularity, Loki is not lost to many characters in the same universe.

 

The charm of villains like them stems from this fearless madness in their hearts.Compared with all the positive characters who have to think twice about justice and the overall situation, people like Loki can be more reckless and go their own way about their persistent things, not only for the audience who saw the movie, but also for the performers, which should be a more enjoyable experience.


Many actors have expressed their desire to challenge the villain.

 

After writing this article, I specially searched the search engine for the keywords "Want to challenge the villain role". Among more than 150,000 related results, a series of familiar actors’ names appeared, such as Lu Han, Haoran Liu, Karry, Liu Shishi, Han Geng, Jiang Jinfu, etc. They all expressed their interest in this kind of role at a certain moment. It seems that there are really many people who have been circled by the villain. On the premise that the three views are correct, we really expect to see more and more classic villains in the future and become another kind of "light" in film and television works.

Trump will be sworn in on January 20 next year to take stock of the "Trump" election road [Photos]



The picture shows the final voting results released by CNN and Trump’s election news. (Screenshot of the page)

The 2016 US presidential election came to an end on the 9th. Republican presidential candidate Donald Trump defeated Democratic presidential candidate Hillary Clinton and was elected as the 58th president of the United States.
Preliminary statistics show that Republican presidential candidate Donald Trump defeated Democratic presidential candidate Hillary Clinton on the 9th and was elected as the 58th president of the United States.
The American presidential election adopts the indirect electoral system of electoral college system. Statistics as of the early morning of the 9th show that Trump has won more than 270 electoral votes needed to win the election. Although the mainstream media in the United States and various polls before the election were obviously optimistic about Hillary, voters expressed different voices with votes. In addition to winning all his dominant States, Trump also won Wisconsin, one of his rival dominant States. In addition, Trump also won more votes than Hillary in Florida, North Carolina, Ohio, Pennsylvania and other "swing states".
Hillary called Trump in the early morning of the 9th to admit defeat. Trump thanked the supporters after winning the election. He said: "I look forward to being your president very much, and I promise I won’t let you down." He also said that the national infrastructure will be rebuilt and called for unity between the two parties.
Darrell West, a scholar at the Brookings Institution in the United States, told Xinhua that "Trump’s victory shocked experts." The white blue-collar and rural population with poor economic prospects voted enthusiastically, which was a major reason for Trump’s victory. They generally believed that the United States had been in the wrong direction. A middle-aged voter named Fan Deng told Xinhua: "This election campaign is very ugly and negative. I am glad that this election campaign has ended." Businessman Rajo said: "I voted for Trump. I believe that he will bring changes to this country. " Hillary supporter Jacquelin told reporters: "This is the last thing I want to see, but this is the status quo in the United States. People’s dissatisfaction with American politicians has reached such a high level. "
During this election, the competition between Hillary and Trump was unprecedented. Hillary was involved in scandals such as the "mail door" and the Clinton Foundation, while Trump was controversial because of his racist and sexist remarks, huge tax avoidance scandals and the operation of foundation donations. The two men’s election campaign, which is mainly based on personal attacks, has seriously torn American society and aroused widespread concern in the international community. This election was called "the ugliest and most divisive" presidential election in recent decades by American media. Before the election, US Secretary of State Kerry admitted that the election process humiliated the United States overseas.
According to the procedure, the new president will be sworn in on January 20, 2017. Trump’s top priority after taking office is to unite the country and repair his image. At the same time, he will face a series of domestic and international challenges such as weak economic growth, widening gap between the rich and the poor, intensified ethnic conflicts and worrying anti-terrorism security. It is reported that the preliminary statistics released by the American media on the 9th show that it is a foregone conclusion that the Republican vice presidential candidate and Indiana Governor Mike Pence will be elected as the new vice president of the United States. On the 8th, the United States also held the re-election of 34 senators and all 435 members of Congress. According to preliminary statistics, the Republican Party has maintained its control over the House and Senate.
Foreign Ministry Spokesperson Lu Kang said on the 9th that China looks forward to working with the new US administration to promote the sustained, healthy and stable development of Sino-US relations for the benefit of the two countries and the people of the world.

Trump’s "surprise" and Hillary’s "shock"
In the early morning of the 9th Eastern Time, the counting of votes in the presidential election, which lasted for a whole day, finally came to fruition. When Donald Trump boarded the podium of the Hilton Hotel in Manhattan, new york, as the president-elect, and delivered his victory speech, the supporters who were hit by the "surprise" could not help but be excited, and many even cried with joy.
Not far from here, in the Javits Exhibition Center, Hillary Clinton’s supporters are trying to get rid of the dizziness after the "shock", and many people are in tears, which makes it difficult to accept the election results.
Just one day before the voting began, the last poll conducted by the mainstream media showed that Democratic candidate Hillary Clinton had 268 "iron votes", and only two votes from the swing state were enough to be elected as the new president of the United States. Trump of the Republican Party, on the other hand, has only 204 "iron votes". If he wants to be elected, he will not only keep the traditional fortress state of the Republican Party, but also get electoral votes from almost all swing states. This is almost impossible from the situation before the election.
Election day is a big day in this country. The TV station set up the stage in Times Square in the center of new york early, and the eye-catching map showed the progress of counting votes. On the big screen of the tall building around the square are huge photos of the two candidates, as well as the real-time rolling progress of the state vote counting. The square is crowded with people full of expectations, and many armed policemen, including the mounted police.
The winning Hillary Clinton team rented the spacious Javits Exhibition Center as the venue for the winning party on the evening of the 8th. At one time, it was originally planned to set off fireworks on the Hudson River. The Trump team rented the Hilton Hotel in Manhattan. Although the venue was not as rich as the opponent, it gave the rally a domineering name: the election night won the election. Moreover, the Trump team rejected all interview applications from international media.
From the beginning of counting votes on the afternoon of the 8th, the situation began to deviate from the expectations of the mainstream media and most people. On the indicator map of the live TV broadcast, the bright red representing the Republican Party slowly spread from the eastern state to the midwest, and Trump almost always kept the lead. In Pennsylvania, Ohio, Florida and other key states, the votes of the two sides are evenly matched in the initial stage. Like wrestling, the opponent is held down for a while and then held down by the opponent. However, almost all the final results ended in Trump’s victory.
When Trump’s vote was close to 200, some of Hillary’s female supporters in the Javits Exhibition Center were a little nervous. When Trump’s votes were close to 250 and he was significantly ahead of Hillary, many female supporters had covered their eyes and dared not look at the display screen, and more and more people wiped their eyes and tears.
After the results of the Pennsylvania vote with 20 electoral votes came out, everything was settled: Trump was sure to exceed the election threshold of 270 votes.
At this time, the boiling in the Hilton Hotel is in sharp contrast with the silence in the Javits Exhibition Center.
Rajo, an Indian businessman who came to the Hilton Hotel to cheer for Trump, said: "I voted for Trump. This guy is not a politician. All the media are against him because he is outspoken. I believe that he will bring changes to this country and will start to deal with illegal immigration. "
At the Javits Exhibition Center, people’s views are diametrically opposed.
Mary Joan said in an interview with reporters: "It’s really shocking to see that guy standing on the stage! He likes to talk about women, discriminate against ethnic minorities, and treat other people’s sexual orientation as talk material, but it is so sad that most people support him. "
Hillary did not return to the Javits Exhibition Center to speak to her supporters. She congratulated Trump by phone and admitted that she lost the election. When Trump made a victory declaration on the stage, he also stopped attacking Hillary and even complimented her.
background
Trump’s main policy proposition
[Taxation] Trump promised to cut taxes across the board and simplify the federal personal income tax rate from the current seventh gear to the third gear. As a result, the highest federal personal income tax rate in the United States will be reduced from the current 39.6% to 33%. In addition, Trump also proposed to abolish the inheritance tax.
[Employment] Trump promised to bring overseas manufacturing jobs back to the United States, advocated reducing the highest federal corporate income tax rate from the current 35% to 15%, and proposed a one-time 10% tax on overseas profits of American companies, and used the income tax to invest in economically backward States in the United States. He advocated the gradual abolition of existing regulations that harm employment, and promised to revive the American coal industry and vigorously develop traditional energy sources such as oil and natural gas, saying that these measures will create 25 million new jobs in the next 10 years.
[Trade] Trump promised to renegotiate the North American Free Trade Agreement, oppose the Trans-Pacific Partnership Agreement (TPP), strengthen trade law enforcement, and impose punitive tariffs on countries that conduct "unfair dumping and subsidies".
[Immigration] Trump promised that illegal immigrants in the United States will not obtain legal citizenship. All illegal immigrants with criminal records and illegal immigrants caught during their administration will be repatriated. He also promised to repeal the executive order on immigration reform issued by Obama in November 2014. The executive order aims to protect about 4 million illegal immigrants who have stayed in the United States for a long time and meet the limited conditions from being repatriated.
[Foreign Policy] Trump summed up the core idea of his foreign policy as "America first", that is, putting the interests of the American people and American security first. He criticized Iran’s nuclear agreement as a product unwilling to leave the negotiating table, and proposed to ease US-Russian relations, use economic leverage to influence other countries’ affairs, reshape US military strength, research and order the most advanced equipment, and let American allies bear more defense costs and even protect themselves.
observe
Despite their differences, China and the United States have sufficient ability to control.
Preliminary statistics released by the US media show that Republican presidential candidate Donald Trump won the US presidential election held on the 8th and was elected as the new US president. What is the American people’s comment on this result? What impact will it have on Sino-US relations and even the world situation? People and experts have something to say.
What do Americans say?
John, a worker, voted for Trump. He said that the reason for doing this is to believe that "Trump will definitely bring changes to Washington."
Statter, a 31-year-old software engineer living in California, is a staunch supporter of Hillary. When he learned the election results, he admitted that he felt "very sad".
On the evening of 8th, a veritable "Tale of Two Cities" was staged in new york. The split of votes represents the different value orientations of the American people.
A survey conducted by Patrick Kader, a senior American pollster, on American voters who may vote in early October showed that Trump had an overwhelming high support rate among white male voters with low income and low education.
Wu Jingsi, an assistant professor in the Department of Journalism, Media and Public Relations at Hofstra University in the United States, said that the result of Trump’s victory made American society, media and many scholars almost "shocked" and even somewhat confused.
"Trump’s victory shows that the American media and society underestimated Trump’s appeal to the American people, especially the low-educated white group. Trump’s so-called "playing cards out of common sense" campaign strategy now seems to have helped him. Although Trump has made many statements that are’ politically incorrect’, the media generally underestimated the tendency of American society to oppose globalization and anti-social trends in 2016, "Wu Jingsi said.
How does Sino-US relations go?
Sino-US relations are one of the most important bilateral relations in the United States, and also a topic of great concern during the US presidential election. What impact will Trump’s election as president of the United States have on Sino-US relations?
Su Ge, president of China Institute of International Studies, said that as the mainstream of Sino-US relations, the depth and breadth of cooperation between the two sides have been increasing, and fruitful cooperation has been carried out on regional and global issues, which has made important contributions to revitalizing the global economy. Under the background of American election, the China issue has been constantly hyped in American domestic politics, but he believes that cooperation is still the correct orientation for the healthy development of Sino-US relations in the future.
Sun Zhe, co-director of the China Project of Columbia University in new york, USA, believes that no matter who is elected in the US general election, the general direction of Sino-US cooperation and the pattern of Sino-US common interests will not change. But he believes that Trump’s most urgent task at present is not diplomacy, but a domestic agenda. Before, for the general election, Trump was strategically "biased", but whether he can introduce practical domestic and foreign policies in time after his election is very important for winning the confidence of voters and later ruling. In this context, there is an adjustment buffer period for Sino-US relations. On the other hand, although China and the United States have differences on some issues, both sides have sufficient ability to control these differences.
What is the impact on the world?
Trump summed up the core idea of his foreign policy as "America first", that is, putting the interests of the American people and American security first. He criticized Iran’s nuclear agreement as a product unwilling to leave the negotiating table, and proposed to ease US-Russian relations, use economic leverage to influence other countries’ affairs, reshape US military strength, research and order the most advanced equipment, and let American allies bear more defense expenses and even protect themselves.
Sun Zhe said that Trump’s coming to power will also have an impact on the global economy and foreign policy of the United States. For example, Trump will introduce some policies to protect the interests of the United States. Therefore, the adjustment of the return of American manufacturing enterprises and trade tariffs may have a certain impact on other countries, but whether this means that the global policy of the United States will shrink remains to be seen.

This year, he was nominated as the best actor in a musical/comedy TV series for "Murder in an Apartment Building", becoming the oldest actor in the award nomination.

How did the property market perform during the Golden Week?

  Xinhua News Agency, Beijing, October 9th Question: How did the property market perform during the Golden Week?

  Xinhua News Agency "Xinhua Viewpoint" reporter

  First-tier cities such as Beishangguangshen and Shenzhen have implemented the policy of "recognizing houses but not loans", and Guangzhou, Wuhan, Nanjing, Dalian, Zhengzhou and Hefei have completely cancelled or partially relaxed the purchase restriction … … Recently, a series of policy combination punches have injected warmth into the property market. What new features and trends have emerged in the real estate market during the Mid-Autumn National Day Golden Week this year?

  Local mild warming, uneven regional cold and hot.

  The reporter visited Beijing, Shanghai, Wuhan, Nanjing, Changsha and other places and found that under the background of the continuous improvement of the policy toolbox for stabilizing the property market and the continuous adjustment and optimization of the real estate policy, residents’ confidence in buying houses gradually recovered, and the property market showed a state of partial moderate recovery and uneven regional heat and cold.

  Xu Dong, a marketing staff member of a real estate enterprise in Wuchang District, Wuhan, told the reporter that compared with ordinary weekends, the sales office of the two-day holiday is very popular this year, and he receives nearly 100 groups of customers every day. "The number of visitors to the house has doubled, and the transaction volume has been relatively stable, with 4 to 5 sets of daily sales." Xu Dong said.

  In Changsha, Ming Bin, deputy general manager of Hunan New Environment Real Estate Brokerage Chain Co., Ltd., was busy for a holiday. "After Changsha recently adjusted its real estate policy, the demand for improved housing increased significantly, and the listing volume and transaction volume of second-hand housing increased significantly." Ming Bin said.

  Yang Jingli, a property consultant of Jianfa Maoyun, a new site in the southwest of Nanjing River, told reporters that hundreds of customers visited the sales office every day during the Mid-Autumn National Day, and transactions were made every day. "Before the New Deal, many people were waiting to see, and after the New Deal, customers with housing improvement needs took shots."

  In a well-known real estate agency in maliandao East Street, Xicheng District, Beijing, Mr. Li, a property consultant, ushered in the busiest day of the Golden Week holiday on October 6. "Some signed the contract once with a look, and the store sold 3 sets a day." Mr Li said with a smile.

  Mr. Deng, who is going through the formalities of buying a house in the store, said that he sold a house in Chaoyang District and replaced a house in Xicheng District. “‘ Admit the house but not the loan ’ After that, I can enjoy the low down payment and low interest rate policy for the first suite, and the housing provident fund loan interest rate is 3.1%; The agency fee has also dropped. Originally, the buyer was required to pay 2.7% of the total transaction price of the house. Now the buyer and the seller each pay 1%, and the intermediary finally gave a 20% discount. "

  "Overall, the property market performed differently during the two festivals. Tianjin, Wuhan, Suzhou and other places have improved their market activity under the housing fair and the New Deal. Shanghai, Guangzhou, driven by the supply side of the real estate, have rebounded; The property markets in Beijing, Shenzhen, Chengdu and Hangzhou are relatively stable. " Chen Wenjing, director of market research at the Central Finger Research Institute, said.

  According to the data of RealData, the average daily turnover of 50 cities in the Mid-Autumn National Day holiday increased by 3% year-on-year, the number of visitors increased by 13%, and the number of new listings increased by 19% year-on-year.

  According to Chen Wenjing’s analysis, from the overall performance of the Golden Week, the enthusiasm of various places to promote sales increased, and the number of project visits increased compared with that before the holiday. At the same time, the market differentiation between cities and regions is more obvious. The heat in core cities and key areas of some cities is higher, and the overall performance of transaction volume is stable.

  Developers fancy push plate, "improving customers" pay attention to quality

  Buying a house to send home appliances, painting contest, drawing gold bars to send gold ornaments, elite blind date, antique market, global food market … … During the Golden Week, Wuhan’s real estate marketing efforts increased, and activities were varied.

  The 41st Wuhan Golden Autumn Online Housing Fair officially opened on September 28th. More than 170 real estate enterprises in Wu Hanyou participated in the online exhibition, with over 300 properties and over 100,000 houses. The reporter contacted Mr. Shen, who chose the house online. He told the reporter: "Recently, the purchase restriction has been released, and several concessions are quite strong, which are being compared and considered. During the housing fair, the purchase of a second house in the participating buildings in Wuhan can be subsidized at 50% of the deed tax payable. "

  According to the statistics of Nanjing Housing Management Department, 4,568 sets of commercial housing in Nanjing were subscribed in September, up 39% from the previous month. Behind the hot sale of real estate, it is inseparable from the profit-making volume of housing enterprises. "Enter the tradition ‘ Silver ten ’ A new wave of opening is brewing. According to statistics, during the Mid-Autumn National Day, 93 properties in Nanjing launched preferential activities to support the accelerated release of rigid and improved housing demand. " Zhang Hui, secretary general of Nanjing Real Estate Association, said.

  The heat of the market is picking up, but the new trend of the property market changing from a seller’s market to a buyer’s market is remarkable. People’s requirements for the quality of living are constantly improving, forcing developers to polish "product power" and work hard on the supply side.

  A research report recently released by Kerry Research Center pointed out that since the beginning of this year, improving the population has become the main force in the real estate market, and half of them are 30-40 years old. The overall education level is relatively high, and the population with more than two home ownership experiences accounts for nearly 60%.

  "Taking advantage of the Golden Week, I want to see more houses and compare the advantages and disadvantages of various properties." Ms. Wang, who transferred from Dongguan to Guangzhou, told reporters that although she has a house in Dongguan, the policy is good now, and buying a house in Guangzhou can be considered as the first set. She wants to "shop around" and choose slowly.

  The reporter visited several buildings for sale in Guangzhou, and found that many projects made a fuss about flower ponds and floating windows, and set up multi-functional balconies with gardens, life balcony and great depth in residential suites, breaking the original functional divisions in apartment design and implementing "integrated" open design to attract potential buyers with innovative products.

  In Shanghai, it is difficult to sell "old and small" houses with poor living environment, but second-hand houses with newer age and better quality are quite popular.

  The policy continues to exert its strength around just-needed and improved needs.

  Many insiders said that a major factor affecting the current property market is the profound change in the relationship between supply and demand of real estate. At present, the policies that have been introduced in various places focus on reducing the burden on buyers who just need and improve their needs. In the next step, the continuous optimization and adjustment of real estate policies, the continuous improvement of policy accuracy, and the continuous recovery of the economy will help to further release the demand for housing.

  "The starting point of the property market policy still needs to focus on better meeting the rigid and improved housing needs of residents." Chen Jie, director of the Housing and Urban-Rural Construction Research Center of Shanghai Jiaotong University, said that some policies applicable to the period when the real estate market is in short supply can continue to be adjusted and optimized, for example, the identification of ordinary commodity housing standards, the adjustment of taxes and fees for second-hand housing transactions, and the integration with birth policy, pension policy and talent attraction policy also have a lot of room for optimization.

  In order to better protect consumers’ rights and interests, more and more cities are taking the pilot steps of existing home sales. Hainan, Chengdu, Hefei and other places clearly support the sale of existing homes, and Shandong, Anhui, Henan, Sichuan, Guangdong and other places have also stated that they will pilot the sale of existing homes.

  What you see is what you get, and the certificate will be handed over as soon as you hand over the house, so you don’t have to worry about the wrong goods … … Yan Rong, president of Shanghai Academy of Real Estate Sciences, believes that the current pilot projects of existing home sales in several provinces can prevent delivery risks and help enhance market confidence.

  "The implementation of existing home sales is an important starting point to promote the transformation of the real estate industry to a new development model, which can break the real estate ‘ High turnover, high leverage and high debt ’ The development model has forced housing enterprises to transform their business models. " Liu Lin, a researcher at China Macroeconomic Research Institute, said. (Reporter Wang Youling, Zheng Juntian, Deng Huaning, Xu Haibo, Gong Liankang)

There are new tricks in the sound synthesizer! The official lineup of "Come and See Our Concert" has caused controversy.

In the current variety market, music variety is not uncommon, and even homogenization has begun to appear. In order to attract more audiences, the music ensemble groups have come up with different concepts, which are mostly divided into rock, folk, pop, electronic and so on according to the types of music.

However, a music ensemble "Come and see our concert" which will be broadcast soon will be innovated in the form of performance, emphasizing that "all-open wheat" will give the audience a closer musical experience. At present, people haven’t walked into the gymnasium for a long time to feel the power of chorus at the concert. The concept of the program just captures the audience’s yearning for live music, which naturally has an advantage over other sound synthesizers.

The program lineup has also been announced recently, covering Chinese singers of all ages, and performing in the form of a combination. The gathering of Jeff Chang Shin-Che, Wu Sikai, Dai Peini and other classic singers is believed to evoke many people’s youthful memories. Pin Guan, who used to be a popular short video platform with "The Door is Unlocked", will also be on the stage with his friends.

Most of these singers are representatives of singers who are more popular than others. The songs they performed spread all over the streets, but no one cares about the singers themselves. I don’t know if they can turn red again in such a sound ensemble that pays attention to the strength of the scene.

However, when it comes to "turning red", the 2007 fast men who are also in the program lineup may be more experienced. Chen Chusheng, Land Rover, Ahu、Yue and Bird, well-known names, have gradually been forgotten after the draft fever faded more than ten years ago. Some of them insisted on their musical dreams, some switched to filming, and some gradually retired … Until recently, the fast men returned to the public view with a reality show. The slow variety show that was not optimistic originally exploded, and the Douban score was as high as 9.7, which also made the fast man in 2007 get unprecedented attention.

No matter what the singing strength is, the story of brothers reunited on the stage for many years is enough to attract the audience. After their complicated lives, the brothers can still get together. The "brotherhood" between them is the key to the recent popularity and the focus of the program propaganda. The slogan "Fast Man" was put on the poster to attract a wave of nostalgic fans and expand the audience.

The program has gathered a lot of powerful singers, and naturally it needs traffic blessing, so the new generation of singers is indispensable. However, after the official announcement of the lineup, the appearance of Vin and imp attracted a lot of controversy. Vin and Cai Weize of the same company formed a "47" group to perform together. Due to the incident that Vin’s father was sued before, many audiences did not have a good impression on him. Critics even call it "rat shit spoils a pot of porridge", and such artists with poor reviews have more or less negative effects on program ratings.

Because of irrational fans and exaggerated costume makeup, Kid Lil Ghost has also been controversial from all sides. His performance style on the stage was exaggerated, and the action of "air guitar" was ridiculed, which most people said they could not appreciate. The punk image that Kid has maintained for a long time is not very suitable for the positioning of the program "All-in-one Mai Power Singer", and singing is not the focus of his performance. In fact, the form of his performance is greater than the content, the lyrics lacking nutrition are criticized, and fans are mostly attracted by the appearance of minority subcultures. If the kids still perform in a way that is always original, it will inevitably lead to a wider discussion and criticism.

However, the program group also spent a lot of time on the lineup arrangement. The partners of the two traffic niche students are Cai Weize and Diamond. Although Cai Weize made his debut as the son of tomorrow series draft, at the same time, as the lead singer of the band, he has good singing skills, and Diamond is recognized as a strong singer in the circle and the audience. The cooperation of partners during the performance can also enrich the stage effect to a certain extent, and more importantly, the collision of different types of musicians can increase the topic and accumulate heat for the program.

It is undoubtedly ambitious to try to make a real "concert effect" sound ensemble, as evidenced by inviting a group of established singers. While the controversial artists have a negative impact on the program, they actually attract more attention for the program, which virtually creates momentum for the broadcast. With the help of the artist’s own traffic and program promotion, many people have noticed this new sound ensemble that is about to start broadcasting. Whether the concert can be moved into the variety stage, as stated in the propaganda, will be seen after the program starts.

Hai Qingxin’s drama is controversial, and the powerful actors also come to this set? It’s not that Tanya is petty.

Produced by Iqiyi and Tencent Pictures, the TV series "Heart Residence" directed by Huatao Teng has been officially launched in Shanghai, based on Teng Xiaolan’s novel of the same name, with Teng Xiaolan as the screenwriter. A few days after the boot, the official announced the starring lineup.

When the starring roles were officially announced on Weibo, they were @ @: Christina, Tanya and Zhang Songwen. The brackets were specially noted behind, which read "Sort alphabetically by name.”。 This is to tell you that the ranking of the actors is only based on the phonetic alphabet, and it is not the potential information of Christina.

By comparing the project book with the investment promotion information, Christina, who was originally clearly regarded as something, somehow announced it in such a way that it was sorted according to the pinyin letters of surnames when he announced the official lineup. Specially, the remarks on ranking the positions make everyone feel very disgusted. Tanya is all under the banner of powerful actors, so how can he make such a petty thing to compete for the positions?

On strength and nationality, the most obvious manifestation of nationality lies in that when we talk about Christina, we can casually talk about several of her representative works: Little Joy, Little Separation, Dwelling House, Mind, Beautiful Times of Daughter-in-law, Double-sided Adhesive and Wang Gui and Anna, as well as the heroine of a movie that broke 3 billion yuan. The douban scores of the above works are all 8, which is the proof of strength.

This time, Tanya, who competed with Christina for the position, has so far exploded a two-time match of Nothing But Thirty and a four-time match of the first part of the great rivers. The two dramas can make her fame soar to this point, and it is also a bonus for those who have greatly eaten these two roles. Compared with Christina’s accumulated experience in the entertainment industry for more than ten years, her achievements are not enough.

I am a few catties, and of course I know best. So why do nursery rhymes fight for this position?

First, the role is changeable

Since Tanya returned to the entertainment circle, she first played a role as a benchmark in Ruyi’s Royal Love in the Palace.Gao guifeiRelying on his father’s contribution, he was bullying in the harem, wearing colorful clothes and looking arrogant. In fact, he was very popular with the audience.

Later, it was in "Big Rivers" that I played the hearts of audience friends.Bai Yueguang Song YunpingHow miserable Lei Dongbao cried in the play, how miserable the audience cried outside;

Nothing But Thirty, who let nursery rhymes kill all the florets from the post-1980s age group and become the first Tsing Yi, won many awards. Her role as Gu Jia in the play was even more amazing. From career to family, I have arranged every inch of my life in order, and my ability to do things is better than that of many women, absolutely.The benchmark for a new generation of independent women.

These roles, whether from the background of the times or the character, have made great strides, and Tanya has done a very good job. Compared with Hai Qing, she has always been shackled by a "daughter-in-law".Tanya, compared with her, is indeed more changeable on the road.

Second, the proportion of role plays is average

Netizens who have read the original novel said that the novel is about a story between a pair of aunts. The roles played by Hai Qing and Tanya respectively are actuallyThe novels are completely accompanied by each other’s growth, and there is no absolute female number one.The opponents of the two people are basically equally divided.

One is that after marrying her husband, she accidentally became a widow and grew up step by step to support this family alone; One is a wayward girl, from flash marriage to flash separation, subverting her understanding of life and family.

The two characters have different outlook on life, and they constantly encounter various problems in their life growth, which can completely show readers two different perspectives and reflect different lives.

Therefore, in TV series, the shaping of these two roles is not a collision with each other, but a complementary state.

Third, the current entertainment atmosphere

The dispute over the position has become very serious up to now.. Even when My People,My Country, a tribute film, exposed the poster of the star, the square composition avoided the dispute over the position, so as not to cause controversy.

In a work, because of the rank, it often corresponds to the influence of the actor and his commercial value. Later, in order to avoid the disputes among fans, countless producers tried to break their heads, such as publishing the starring lineup according to the age method, publishing the starring lineup according to the first capital letter of the name, and publishing the casting lineup according to the order of appearance. There are no other innovations, and my head is all used in this area.

In that case,The whole entertainment environment is like this.Others can argue, why can’t Tanya?

Although it is said that the popularity of this drama has not caused much waves, it was only limited to the behavior of traffic stars before, and it has evolved into a powerful actor, which still makes many netizens feel that the happiness of chasing the drama has been disturbed. On-Moon Arc

Create a global future community and paint a beautiful picture of urban and rural areas … Tonglu iteratively builds the most beautiful county in China with a future vision!

City Express News Yesterday, the on-site meeting of the improvement of urban and rural features and the future community construction in Tonglu was held.
As the host, Tonglu invited representatives from all over the province to visit Yingchun South Road, the city exhibition center, Fuchun Future City and other places. All the way from the high-speed entrance to the county center and then to the rural border, the "beautiful urban and rural landscape of the whole region" of the most beautiful county in China is slowly unfolding.
There are 1409 villagers in the village, but there are 4100 beds.
This is the "beautiful countryside 3.0 Pioneer" where every family runs a farmhouse.
Lutz Village, located on the bank of Fuchun River and across the river from Yan Ziling Fishing Terrace, is the "most lively" stop in the inspection route.
On the way to this "the first rural slow life experience area in the province", you can see beautiful landscapes everywhere. As soon as you enter the village entrance, the car is full of excitement.
"Today is not Thursday? There are so many tourists! "
"From the window, it seems to be all homestays, and the buildings are very distinctive."
Lutz village, relying on rural tourism and farmhouse hotel industry, makes economic development enter the fast lane.
"Lutz Village covers an area of 54.5 square kilometers, with 1,409 villagers and more than 4,000 beds. Up to now, there are 184 homestays in the village, and it is hard to find a room during the tourist season in July and August. In 2020, the number of rural tourism receptions reached 1.98 million, and the tourism in operational income reached 136 million yuan. "
The commentator’s voice just fell and the scene became lively again.
"That is to say, more than 5,000 people come here every day on average?" "It’s amazing that a village can have such reception capacity!"
Lutz village was originally a little-known hollow mountain village, "seeing the scenery but not the gold".
Nowadays, it is a well-known ecological village, art village and tourist village, which not only makes the development of tourism and leisure industry with village characteristics more reasonable, but also embarks on the road of sustainable development. It has also won honors such as national democratic and legal village demonstration village, Zhejiang farmhouse demonstration village and Zhejiang characteristic boutique village.
Standing at a new starting point, Lutz Village has implemented 16 projects of "five big villages" such as "people’s wisdom and brains", art fields and express post stations, constantly polished the brand of "Lutz Red", formed a pioneering place of beautiful countryside 3.0 integrating five elements of numbers, entrepreneurship, art, rule of law and civilization, and is striving for the goal of building a future village.
From the "transformation" of Lutz Village, we can see the direction of Tonglu’s iterative upgrading of beautiful countryside 3.0: stick to the development road of "Lucid waters and lush mountains are invaluable assets", combine green ecology with rural revitalization strategy, and let the concept of developing beautiful economy penetrate into the hearts of everyone in Tonglu.
5 minutes to work, 10 minutes to school, 15 minutes for fitness and leisure.
This is a "global future community" where everyone can reap a small fortune.
"Future community" is a high-frequency word at this meeting.
What is the future community? It’s that residents have good houses, that life is more convenient and facilities are more intelligent …
On the basis of the future community, Tonglu described the blueprint of "Global Future Community".
East to Baoxin Road, south to Hanghuang Railway, west to Meilin Road and north to Yunxi Road, with a planned area of 4 square kilometers. This piece of land, which is planned as Fuchun Future City, is located in the core area of Tonglu County, and is the model land of Tonglu’s "global future community".
What is the global future community of Tonglu?
Fuchun Future City will build high-quality residential buildings, introduce high-quality educational resources, relocate Tonglu First People’s Hospital, attract 170,000 square meters of the largest Yintai City commercial complex in western Zhejiang, promote the comprehensive passenger transport hub with zero transfer to high-speed rail, and build the first professional express logistics exhibition center in China …
"From the future community to the global future community, it is a transformation from’ community’ to’ urban area’, which will be the global application of the living circle, the concept application of the three-in-one-nine scenario, the global application of indicators and the global linkage of government work. Here, the life circle of’ 5 minutes to work, 10 minutes to school, 15 minutes for fitness and leisure’ will be realized. " The relevant person in charge of Fuchun Future City said.
In addition to improving the intelligent supporting construction, the construction of Fuchun Future City will give full play to the advantages of Tonglu express delivery industry, adhere to the principle of industrial agglomeration, rely on the return advantage of "three links and one access" chain owners, gather and develop the "1+3+X" industrial system led by the whole industrial chain economy of express logistics industry, and continue to empower the chain owners’ innovation chain, manufacturing chain, service chain and financial chain with the combination of chain building, chain strengthening and chain supplementing.
"The overall construction sequence of Fuchun Future City is’ laying the foundation in one year, achieving results in three years and basically completing it in five years’. We started the construction of key projects in 2019, and it is planned that by the end of 2023, everyone will be able to see the basic appearance of the future community in the whole region."

Democratic Progressive Party authorities received more than NT$ 800 million in donations after Hualien’s severe disaster. Zhanjiang Village: When will it stay?

The Straits Herald comprehensively reported that the Matai Anxi dammed lake on the island broke its banks and caused disasters. More than 1,800 households were affected by the disaster in the Guangfu area of Hualien, and the Taiwan health authorities announced on the 4 th that their donations totaled 900 million yuan (NTD, the same below). Taoyuan City Councillor Zhan Jiangcun questioned why the donations received by the Democratic Progressive Party authorities were not directly distributed to the victims. Until what time?

On the 4th, Zhan Jiangcun said on Facebook that the donation from Hualien County Government will be distributed on October 3rd, and each victim will receive 50,000 yuan from solatium. Democratic Progressive Party authorities have received more than 800 million donations. Why not give them directly to the victims? Until what time? How to use it? Democratic Progressive Party, say something!

Netizens have left messages saying, "Now I have donated money, but I can’t use it? What’s the matter? The incompetent authorities still cry for poverty all day, but now there are so many donations, so they don’t give them to the affected households quickly. Jade Bird goes around telling others not to donate money to the Hualien county government, and also monitors whether the counties and cities have given it to the victims, so they will keep their mouths shut. I don’t think much about the 800 million yuan, but I will know with my navel and fully monitor where the donations are spent.

Light | Matrix Multiplication Photon Accelerator and Its Application

Written by Cheng Junwei (Huazhong University of Science and Technology)

In recent years, with the increasing demand for data processing by artificial intelligence and the fifth generation communication, the data computing capacity and computing power consumption have increased rapidly. The clock frequency of traditional electronic methods is generally limited to several GHz, which can no longer meet the needs of ultra-high speed and low delay mass data processing. On the other hand, with the failure of Moore’s Law, it becomes more and more difficult to improve their performance and energy efficiency by relying on semiconductor electronic technology.

Due to the continuous and substantial increase of information capacity, in the foreseeable future, the general electronic processor is difficult to be competent for high-complexity artificial intelligence and signal processing tasks. butmatrix calculationIt is one of the most widely used and essential information processing tools in science and engineering.

Most signal processing, such as discrete Fourier transform and convolution operation, can be attributed to matrix calculation. The main feature of neural network algorithm, especially represented by deep learning, is that it contains heavy matrix calculation. Taking convolutional neural network as an example, its matrix calculation overhead can account for 80% or even more than 90% of the total overhead. Accelerating and optimizing matrix calculation can greatly improve the calculation efficiency and power consumption of signal processing and artificial intelligence.

Photonic devices have ultra-large bandwidth and ultra-low power consumption, the frequency of light can reach 100 THz, and there are many free physical dimensions, which makes photonic computing one of the most competitive candidates in high-capacity and low-delay matrix information processing in the post-Moore era. In recent years, photon matrix multiplication has developed rapidly and is widely used in the fields of photon acceleration such as optical signal processing, artificial intelligence and photonic neural network. A large number of applications based on matrix multiplication show great potential and opportunities in the field of photon accelerators.

Fig. 1 conceptual diagram of matrix multiplication photon accelerator

Recently, fromHuazhong University of Science and TechnologyThe research team, andChinese University of Hong Kong, University of Shanghai for Science and Technology, Zhejiang UniversityandXizhi technologyA number of research scholars have cooperated to "Photonic matrix multiplication lights up photonic accelerator and beyond"For the topic, in Light: Science & Applications A summary article on the theme of matrix multiplication photon accelerator was published in.

Photon matrix-vector multiplication classification

At present, the mainstream photon matrix-vector multiplication (MVM) mainly includes three categories, namely, matrix calculation based on (single/multiple) plane optical conversion (PLC), matrix calculation based on Mach Zehnder interferometer (MZI) network, and matrix calculation based on wavelength division multiplexing (WDM). Among them, the matrix calculation of plane transformation is divided into single-plane matrix calculation (SPLC) and multi-plane matrix calculation (MPLC), both of which belong to coherent calculation, and the reported input vector length can reach the order of 357 and 490,000 respectively. The output vector length of MZI and WDM methods is generally less than 100, which is mainly used to integrate photonic matrix computing chips. These methods mainly calculate the matrix based on the spatial dimension or wavelength dimension of photons, and can also combine multiple dimensions of photons to construct ultra-high-capacity photon tensor core.

Fig. 2 Classification of Photon Matrix Multiplication

Accelerate application of photon matrix-vector multiplication

Photon matrix multiplication network itself can be used as a general linear photon loop for photon signal processing. In recent years, MVM has become a powerful tool for various photon signal processing methods. MPLC-MVM benefits from its ability of large-scale matrix calculation, which can manage a large number of patterns, can be used as a general pattern classifier, and the scale of its operating patterns can reach hundreds. It can also be further extended to realize the simultaneous control of multiple classical physical dimensions of photons, and can be used in applications such as spatial imaging encryption. MZI-MVM is easy to integrate, and because of the high speed of phase shifter, it can realize the automatic configuration of MZI grid function, and can be used as an adaptive mode processing device to realize free uploading, downloading, multiplexing and demultiplexing of multiple modes and channel descrambling. WDM-MVM takes up less space and is easier to configure the transmission matrix. It has been applied to programmable pulse shaping, micro-ring weight library and signal component analysis.

Figure 3 Application of Photon Matrix Multiplication

Artificial intelligence technology has been widely used in various electronic industries, such as speech recognition and image processing based on deep learning. As the basic component of neural network, matrix computing takes up most of the computing tasks, for example, the computation of GoogleNet and OverFeat models exceeds 80%. Improving the performance of the matrix is one of the most effective ways to accelerate the neural network. Compared with electric calculation, optical calculation is poor in data storage and flow control, and the low efficiency of optical nonlinearity limits the application of nonlinear calculation such as activation function. Then, through wavelength, mode and polarization multiplexing technology, optical methods have obvious advantages in large-scale parallel computing, and have extremely high data modulation speed and low delay. Therefore, photonic network is very suitable for matrix calculation. The combination of optical computing and artificial intelligence is expected to realize intelligent photon processor and photon accelerator. In recent years, artificial intelligence technology has also developed rapidly in the field of optics. All kinds of photon matrix calculations have been proved to be able to replace the linear part of neural network algorithm, and its single core has been proved that the calculation capacity can exceed 11TOPS, the delay of photon matrix calculation is generally in the order of picoseconds, the energy consumption of a single multiplication and addition operation is in the order of defocus, and the signal modulation rate can be as high as 100 GHz. Compared with electronic computing, it has obvious advantages in speed, delay and power consumption.

Challenges and prospects

At present, there is still a huge gap between photonic matrix calculation and electronic calculation. In order to solve this problem, one of the direct and effective solutions is to manufacture large-scale photonic integrated circuits. Similar to integrated circuits, the improvement of manufacturing technology provides an opportunity to realize photonic integrated circuit chips with larger scale and higher integration density. In addition, by using multiple free dimensions of photons, such as modes, wavelengths, etc., optical devices can perform a large number of parallel calculations, which can be performed in a physical photon calculation core. At the same time, we can expand the network scale by optimizing photonic devices, such as spectrum reuse strategy, higher modulation speed and lower power consumption modulator, low loss waveguide, hybrid integration and so on.

 

Matrix calculation and activation function are two basic operating elements of neural network model. Photon matrix calculation has obvious advantages over electronic methods in signal rate, delay, calculation density and power consumption, but the photon activation function is still immature. At present, it is mainly divided into optical-electrical-optical conversion method and all-optical method. How to realize the activation function with low power consumption and high response rate in the future is still a difficult problem.

Before all-optical artificial neural network matures, especially before optical nonlinear effect and all-optical cascade maturity, photoelectric hybrid artificial intelligence computing is still a more practical and competitive candidate architecture for deep artificial neural network. Therefore, it is one of the core research paths of photonic artificial intelligence to develop an efficient and dedicated optoelectronic hybrid artificial intelligence hardware chip system. In the future, the bottom hardware of accelerator can be realized based on photon matrix calculation and electronic control, and various algorithms suitable for this hardware can be developed. Finally, these algorithms can be flexibly called in the user layer to realize various accelerated applications, such as channel descrambler and image recognition.
