In the Beijing Opera "Shiro Visits Mother", the princesses and maids of the Liao Dynasty are dressed in the costumes of the Qing Dynasty, because this shows that they are different from the Han people. The costumes of Chinese opera are stylized, and there is no distinction between dynasties and seasons. On the one hand, it is for the convenience of economy and performance, on the other hand, it is impossible for artists to research what historical figures wear. Fan Han and Fan Han are different. For example, a fox's tail means a nation. The reason why Peking Opera wears flag clothes is that Peking Opera was formed in Beijing and often performed in the palace. Influenced by the flag bearer, the flag costume was used to represent the woman of Fanbang, whether she was a flag bearer or not. The same is true of Hebei Bangzi and Pingju, which are greatly influenced by Beijing Opera ~
