What kind of drama expression is changing face?

Changing face is the way of performance of China Sichuan Opera.

Sichuan Opera is very popular in Sichuan, Chongqing, Guizhou, Hubei and Yunnan provinces. The performance mode of "changing face" in Sichuan Opera originated from the traditional drama "Guizhenglou", which shows that the righteous thief Bei Rong robbed the rich and helped the poor, was chased by officers and men, and got away cleverly by changing face. There are three ways to change the face of Sichuan Opera: wiping face, blowing face and pulling face. The magic of Sichuan Opera's "changing face" is that in the process of lifting, wiping and waving with one hand, one face after another is replaced.
