Caijiawa Wuyin Dagu is a form of folk art popular in Miyun District, Beijing. Its predecessor, Wuyin Dagu, was popular around the Qianlong period of the Qing Dynasty. It was first performed in the palace as a self-entertainment in the form of "Qingyinhui". Later, it spread to the people and was spread by artists to the southern part of Beijing, Tianjin, and Xinglong and Anci (now Langfang) in Hebei. Among them, the branch introduced to Anci mutated and gave birth to the "Single Qin Dagu" or "Beijing Qinshu"; and the branch spread to Xinglong, Hebei and nearby Miyun, Beijing, was completely preserved in the Wumudi natural village of Caijiawa Village, Jugezhuang Town and its surrounding areas until it was "rediscovered" in 1998.
