The sheng has numerous subtypes. The two major subdivisions are the laosheng and xiaosheng, with another important subtype being the wusheng. Peking opera troupes will always have a laosheng actor. A xiaosheng actor may be added to play roles fitting to his age. In addition to these main sheng, the troupe will also have a secondary laosheng.
Laosheng
The laosheng is a dignified older role, usually distinguished by a long, thin, three-part beard. These characters have a gentle and cultivated disposition and typically wear long robes with water sleeves, high-soled boots, and fabric headdresses. A subcategory is wulaosheng, older generals who have combat skills. They wear armors and helmets instead of robes and fabric hats. Guan Yu, the Chinese god of sworn brotherhood, loyalty and righteousness, and Zhao Kuangyin, the first Song dynasty emperor, are the only 2 characters in the subcategory known as hongsheng, a red-faced older male.
Xiaosheng
Young, beardless male characters are known as xiaosheng. They wear paler makeup than laosheng characters to show their youth. Xiaosheng characters are often involved with beautiful young women by virtue of the handsome and young image they project. Depending on the character's rank in society, the costume of the xiaosheng may be either elaborate or simple. In Peking opera, these characters sing in a high, shrill voice with occasional breaks to represent the voice changing period of adolescence. The subcategories of xiaosheng are the wenxiaosheng and the wuxiaosheng. The wuxiaosheng roles possess martial skills and are frequently young generals. Often, their filigree helmets are appended with two long pheasant feathers known as lingzi.
Wusheng
The wusheng is a martial character for roles involving combat. They are highly trained in acrobatics, and have a natural voice when singing. In Peking opera, wusheng is further divided into 2 subcategories based on the character's costume:
The changkao wusheng are high-ranking warriors who wear armors, helmets, and high-soled boots. They mainly use prop weapons.
The duanda wusheng are individual fighters or disenfranchised criminals who wear tight jackets and trousers known as kuaiyi or baoyi and thin-soled boots. Some of them wear a beret known as luomao. They are more likely to engage in hand-to-hand combat.
Cross-gender acting
In Yue opera, sheng roles have been mainly portrayed by actresses. Actresses playing men is also common in some southern genres like Teochew opera and Taiwanese opera. It also appears in Ping opera. In Peking opera, Meng Xiaodong was perhaps the first female superstar who specialized in sheng roles.
