The classic oil painting "Yu Gong Moves a Mountain" created by Xu Beihong was sold for RMB 33 million yuan on the 26th, breaking the highest domestic price record for Chinese oil paintings. It also broke the myth that high-priced artworks could not be sold online. This is also the world's highest auction sale via the Internet. However, the national treasure "Yu Gong Moves a Mountain" failed to return to the motherland and was lost overseas again.
