If it were not for the number of famous painters in history, the answer to your question might be Songzhuang Town, Beijing.
Songzhuang Town is located in the east of Beijing, the capital, and in the north of Tongzhou New City. Songzhuang Town has rich cultural resources, with nearly 2,000 artists in painting and calligraphy. Songzhuang has become the largest and most famous painter village group in Beijing and even in China. In 2006, the Beijing Cultural Expo named China's Songzhuang as the Beijing Cultural and Creative Industry Cluster and the 2006 Best Cultural and Creative Community.
As the artists gradually formed a large scale, Songzhuang began to be called the "Painter Village" and became the largest community of original artists in China. What was originally a simple residential gathering place for artists has gradually developed into an art gathering area for original artists, galleries, critics and agents.
