Did Qi Baishi, who bought it in Tik Tok, really paint it as reflux?

No, Qi Baishi's paintings are traditional Chinese paintings with the characteristics of traditional ink painting in China. They are based on traditional ink painting, flowers and birds, fish and insects. It is not true that some people sell Qi Baishi's fakes in the name of "returning from overseas" or "Collection of Baishi Disciples". Some auction companies in China have collected a lot of Qi Baishi's paintings and calligraphy from Japan, but there are few original works.
