Crosstalk is one of the most popular and popular types of folk art, known for its humor, satire and drama. It was formed in Beijing during the Xianfeng and Tongzhi periods of the Qing Dynasty, and then spread widely in the vast northern region, especially in the Beijing-Tianjin area. It has been passed down to the ninth generation. There were originally two types of crosstalk performances. The performance behind the curtain was called "Anchun", which mainly featured ventriloquism programs; the public performance was called "Mingchun", which mainly featured language programs. The crosstalk performance forms belonging to "Mingchun" include three types: single-person stand-up crosstalk, two-person crosstalk and group crosstalk performed by three or more people, and crosstalk is the most common. In the performance text of crosstalk, the actors are divided into A and B, A is responsible for the funny part, and B is responsible for the supporting part. In terms of performance, crosstalk can be divided into several types, such as "one-sided", "mother-child" and "guankou". In recent years, new forms of performance with strong comedy colors, such as costume crosstalk and crosstalk sketches, have also emerged. The traditional crosstalk pieces are extremely rich. After processing and sorting, the main ones that have been preserved are single-talk works such as "Three Levels in a Row", "Pearl Jade White Jade Soup", "Waxing Cane", and "Little God", crosstalk works such as "Praise the House", "Funeral Meeting", "Man Han Banquet", "Yellow Crane Tower", "Guan Gong Fights Qin Qiong", "Drama Talk", "Riddles", and group works such as "Stripping the Jacket" and "King Kong Legs". Tianjin crosstalk is a school of its own, mainly based on speaking, known for satire, fiery and passionate, and full of humor. Works such as Zhang Shoushen's "Gan Zhengbu", Xiao Mushroom's "Tooth Powder Bag", Ma Sanli's "Opening a Porridge Factory", "Selling Tickets", and "Buying Monkeys" are highly satirical and are representatives of Tianjin crosstalk. Tianjin's Wengen crosstalk also has a long history and tradition, and many different performance schools have emerged one after another. For example, the traditional crosstalk "Wenchanghui" has several performance scripts, such as Zhang Shoushen, Ma Sanli, Su Wenmao, etc., and each has its own style when performing on stage. Nowadays, crosstalk is gradually moving towards the edge of "fast food culture" and has become alienated to a certain extent under the influence of mass media. At present, the cultivation of follow-up forces has become a top priority for the inheritance and development of crosstalk, and it needs to be highly valued.
