Can you briefly introduce what is particular about using the corner mask in traditional Chinese opera?

In fact, movies are not difficult. One is to have good enough elm shavings, and the other is to have technology. Just soak the shavings in water in proportion and scrape the film. The makeup of Beijing opera is very unique. Sheng Dan's face is not crooked, but it is not easy to make up. Both men and women want hanging eyebrow, and then draw raw horns and wrap them in a net towel, with their hair tossed and their mouths twisted; Take powder, smudge, eyebrow eye painting, Baotou, film pasting, headdress and so on. Painting faces requires special makeup, including big painting faces (clean), two painting faces (clean) and three painting faces (small painting faces and ugly faces). The most complicated facial makeup is a large painted face. It is said that the origin of Facebook can be traced back to the "face generation" of Lan Ling, a warrior in the Northern Qi Dynasty. Later, the mask appeared on the stage. The mask affected the performance and gradually changed to a hook face. The facial makeup in Peking Opera is an exaggeration of skin color, eyebrows, eyes, nose and mouth, highlighting the texture of bones and muscles, thus achieving the effect of "praising and criticizing good and evil". In a word, Qing Jiao and Hook Face are the representatives of the characters in the play.
