Why is Van Gogh's most famous work sunflower?

Van middot Gogh (1853-1890), a famous dutch painter, is one of the representatives of Impressionism after the 19th century. Sunflower is the most famous work of Van Gogh, which shows the two most remarkable features of Van Gogh's high technique: one is that he uses the brush to draw angular and brittle strokes to express his intense character and create a tense atmosphere in the painting; the other is that he uses the thick painting method to make the painting have the effect of sculpture. The main tone of the painting is yellow, plus a little cyan and green. Although the exciting power of the painting depends on the contrast between yellow, cyan and green, the main reason is that the painter gives the object rich emotional connotation and great spiritual power. Never in the history of painting has such an exciting effect been expressed so strongly in a still life. In the 1980s, in the auction market of ancient paintings in London, it beat Qunfang and sold at a high price of 39.9 million US dollars, setting a record for the auction price of ancient paintings. Sunflower has become an immortal world famous painting. Xiangri CAI in Van Gogh's works is not only a plant, but a life with primitive impulse and enthusiasm.
