Nationality: Whether it is poetry, prose or novels, there are always some events that reveal some local customs and cultural landscapes, while some things are unique, such as the Water-splashing Festival of the Dai people, the Torch Festival of the Yi people, and the Nadam Conference of the Mongolian people ... On a large scale, the characteristics of the eastern nationalities, including religion, architectural style and political system, have their own unique places, which is nationality.
Regionality: In fact, it is a supplement to the above two points, namely, Xintianyou in northern Shaanxi, Huangmei Opera in Anhui, Allegro in Tianjin, duet in Northeast China ... and of course, the quintessence of Beijing Opera, which is a cultural and artistic form caused by unique regional cultural differences. One side's soil and water feed one side's people, and at the same time it breeds one side's culture.
