What do you mean by speaking, learning, teasing and singing in cross talk?

Crosstalk originated from folk songs and dances in northern China and became popular in the Ming Dynasty. Crosstalk is about "telling, learning, teasing and singing", and "telling" refers to jokes, stories, riddles and shouting; "learning" refers to learning human speech, bird language, city sound and crying; "Teasing" refers to gagging and teasing; "Singing" refers to singing "Taiping Lyrics" and opera minor, and crosstalk performers regard "speaking, learning, teasing and singing" as the "four major subjects" for cultivating crosstalk performers.

First of all, I want to know whether an actor can't sing and won't give up singing Taiping lyrics. Speaking, learning, teasing, singing, teasing and singing are skills in themselves, which are the classification of verbs, not the types of songs. Singing is not specifically mentioned, but a skill. Secondly, I totally agree with Degang Guo's point of view. Singing Beijing Opera means learning to sing. I can only say that the skills of learning to sing have been applied here, not learning to sing.

Some Beijingers deride people who come to work in Beijing from these places as "cowards" and mistakenly call them "cowards with a mouth full of grasshopper seeds and two legs covered with loess mud", which has obvious contempt. Later, it developed to imitate Shanxi dialect, Jiaodong dialect, Tianjin dialect, Baodi dialect and Tangshan dialect. In the early 1930s, it expanded to Shanghai dialect, Suzhou dialect and Cantonese. After liberation, Chinese words imitating foreign tastes and Mandarin spoken by overseas Chinese also appeared. They learned to make a hullabaloo about doing small business, also called the sound of goods, mainly imitating selling large and small fish, tea eggs, smoked fish and fried gluten.

Crosstalk is to practice language rhythm through tongue twister or tongue piercing. In fact, "speaking, learning, teasing and singing" is not a scientific classification method, which can neither summarize the content of cross talk art nor explain the expression of cross talk art, and there is no logical relationship between them.
