Secondly, in common operas, whether in Beijing Opera, Shaanxi Opera, Henan Opera, Huangmei Opera, Jiangxi Opera, Sichuan Opera and Cantonese Opera, or in the clown role, students are mostly young and martial arts students. Because of a crime (crime), one loses one's hat, is captured, takes off one's hat, or waits for beheading in the execution ground or is punished in court. Young students or martial arts students are stripped of their hats, revealing a bunch of long hair tied to their heads, also known as a bun or hair tip.
