What's the difference between crosstalk, duet and sketch?

Crosstalk is a folk art, which makes the audience laugh by telling jokes or interesting questions and answers. It evolved from "Xiang Sheng" in the Song Dynasty. In the later period of Beijing School, crosstalk formed modern characteristics and styles. Mainly in Beijing dialect, there are also "dialect crosstalk" in local dialects. "Speaking, learning, teasing and singing" are the basic artistic means of cross talk tradition. "Speaking" refers to telling jokes and tongue twisters, "learning" refers to imitating all kinds of hawking, chirping of birds and animals, singing of dramas and styles and languages of various characters, and "teasing" refers to making up some funny words, singing them in various tunes, or exaggerating some lyrics and tunes of operas to make people laugh.

Crosstalk generally has the characteristics of sketch, humor and wit, and other similar characteristics, but the difference is that: Crosstalk is "about learning, Doby", focusing on "talking", generally without props and makeup; The sketch should not only use props, but also make up, focusing on "acting" and achieving the effect through performance. Talking more and doing less is easy to make people think of cross talk; Acting without talking became a pantomime.
