生行
京剧中的"生"，一般指剧中扮演男子的演员，其中又可细分为"老生"、"小生"和"武生"。"老生"，顾名思义就是中老年男子角色，在剧中多扮演正直刚毅的人物形象，例如京剧《伍子胥》中的伍子胥.他们演出时要戴挂在耳朵上的假胡须，在京剧的行话中也叫"髯口"，因此还专门有一套髯口上的表演功夫。胡须的颜色表示了人物的年龄。京剧《四郎探母》中的杨四郎年约三十岁，所戴胡须为黑色。京剧《秦香莲》中王延龄年约六十，所戴胡须为白色。老生在剧中一般注重演唱和细腻表演，唱腔上也最为丰富。台词用京剧中的韵白来表现，演唱用真声，风格刚劲、挺拔、质朴、醇厚，动作造型也以雍容、端方、庄重为基调。与老生相对应的是"小生"，在京剧中指青少年男子角色，他们在剧中的动作造型儒雅倜傥、秀逸飞动。在演唱上采用真假声结合的唱法，演唱风格华美和明亮。例如京剧《白蛇传》中的许仙"武生"是指扮演剧中年轻的男性武将，他们用高超的武打技术来展示剧中人物的武艺高强。不重演唱，注重武打动作的娴熟和技巧的难度。例如京剧《长坂坡》中的赵云.
Role of Sheng

Sheng, a male role, usually a leading one, dates back to Southern Drama of the Song and Yuan Dynasties (960-1368). This role appears in operas in all historical periods. According to the age and social status of the characters, Sheng falls into five sub-groups: Laosheng, Xiaosheng, Wusheng, Hongsheng and Wawasheng (characters of children). Laosheng is also known as Xusheng, meaning bearded men, because the actors wear artificial beards, and they are middle-aged or elderly men. Most are upright and resolute characters. They sing in their natural voices, and their actions are serious ones. Xiaosheng is a sub-category of Sheng representing young male characters. They don't wear artificial beards. They always sing in their real voices, while in Kunqu and Pihuang operas the singing mixes natural and falsetto voices. Wusheng stands for all of the male characters who appear in battle scenes. They are further subdivided into Changkao Wuheng, Duanda Wusheng, Goulian Wusheng and Houxi Wusheng. They always wear helmets and thick-soled boots. The generals always carry long pikes. Wusheng roles call for sturdy and vigorous actions, with resounding declamations. The movements of the waist and legs are powerful, and a high level of martial arts skills is demanded in these roles. Duanda Wusheng roles use short-handled weapons, and their movements are light and swift.
