The Shanghai Municipal Bureau of Culture and Tourism recently revealed that 37 pieces of cultural relics and artworks from 9 overseas exhibitors, including Christie's, in the cultural relics and artworks section of the consumer goods exhibition area, reached a purchase intention at the Expo this year, with a total turnover of 490 million yuan. When introducing these cultural relics and artworks, some media highlighted Zhang Daqian's Modern Girl and Mark Chagall's Sky in Paris. Modern Girl has a strong background of the times. After the victory of the Anti Japanese War, Zhang Daqian was ecstatic and strived for innovation. He once said, "It is not that modern things cannot be used in Chinese painting. Many modern things, such as western-style houses and cars, can actually be used in painting." Because of this, Zhang Daqian's modern girls, together with traditional trees, bamboos, plantains and flowers, bring a new wind of imitating Buddhism. The Modern Girl displayed at the Expo shows this new trend. Visitors gathered here to feel the "tide" of traditional Chinese painting masters. The Sky in Paris was created by Mark Chagall when he was 93 years old. The artist in the lower right corner of the painting is holding a drawing board and painting still life flowers. Mark Chagall's first wife Bella died young, and he has been remembering her all his life, because Bella likes flowers, and flowers often appear in Mark Chagall's works. Stopping in front of the Paris Sky, it is not difficult to feel the rich and hot emotion in the painter's life experience. At the Expo, cultural and artistic masterpieces gathered. Among the exhibits of the "falling hammer" trade, there are works of oriental artists such as Zhang Daqian's "Modern Girl", Huang Binhong's "Tiaoxi Fishing Hidden", Fu Baoshi's "Red Cliff Boating", Lin Fengmian's "Dahlia", as well as western masterpieces such as Mark Chagall's "Sky in Paris", Edward Monk's "Model on the Vine Chair", and Banks's "Love in the Air". With the integration of East and West, mutual learning of cultures, masterpieces and a gathering of talents, the Expo will not only become a top art auction and trading platform that attracts worldwide attention, but also become an opportunity for audiences to enjoy masterpieces from East and West in close proximity and in batches. Along the Huangpu River, the organic integration of art circulation and display has become a grand occasion of international cultural exchange. At this Expo, top auction houses at home and abroad gathered, and many famous treasures gathered. This is related to the continuous implementation of the "five duty-free" policy for artworks, collections and antiques in the Expo, as well as the public's demand for top artworks. There is a rule in the development of the international art market. When a country's per capita GDP exceeds 3000 dollars, there will be a demand for culture and art. On the one hand, this demand is reflected in the trade and circulation of works of art. Taking Shanghai as an example, the total trading volume of Shanghai's cultural relics and works of art market will reach 35.4 billion yuan in 2021, still 5.4% higher than the previous year in the context of the epidemic; On the other hand, it is reflected in the aesthetic needs of the public - the cultural relics and artworks section has become the most artistic and cultural exhibition area for the Expo every year. Many people go to the world famous works to linger and punch cards enthusiastically. Compared with some bidders, what the vast majority of audiences take away is not tangible goods and predictable business opportunities, but spiritual pleasure and enjoyment of beauty. Art is not a hobby of the minority, but human ideology and culture
