How many stages has crosstalk gone through so far?

Crosstalk originated in Beijing and flourished in Tianjin. The comedian's evaluation of crosstalk should be based on some books and TV broadcasts. I am a wild cross talk bastard in Tianjin. Let's call it a funny corner. Far away, let's say that crosstalk in Tianjin Teahouses has been very popular in the 1980s and 1990s, and it has never declined, but it didn't enter the spread range of mass media such as TV at that time. But at that time, the teahouse culture in Tianjin became a unique temperament, just like those young artists like some minority songs now. Degang Guo is not a pioneer of small theaters, which have always existed in Tianjin. He just brought Tianjin crosstalk to Beijing. As early as the period of red terror, Beijing crosstalk has become a tool of the authorities, and it is not worthy of being called crosstalk. But as far as the development of Deyun Society is concerned, the end will not be too far away (the end I am talking about is not bankruptcy, but the departure from the origin of cross talk). There is a simple reason. After Cao He, Degang Guo never had a disciple with excellent basic skills, so that he could live a down-to-earth life. You can call it a successor. Now I am old, as can be seen from my works in recent years. I have to feel sorry when I write here. Crosstalk is like pancake fruit. Once out of Tianjin, it will never be the same again. Besides, I have listened to Van Gogh II's cross talk since I was a child. His works are mainly satirical, and the classic Fishing, Lessons and Unhealthy Wind are all bitter satires. It is a bit unacceptable to laugh at the people without textual research. Finally, talk about the origin of cross talk. Any art form is not invented by one or two people out of thin air, but evolved through a long process. Although the evolution of crosstalk is not long, it has gone through at least two generations. And the so-called Zhang Sanlu began to cross talk, in fact, it was just that he began to have the bottom of the sea. The earliest origin of crosstalk can be traced back to Eight-Nation Alliance's occupation of Beijing, when the eunuchs in the palace were forced to leave the palace, but they had no livelihood. Fortunately, I can tell a few jokes when I wait on my master again, so I can make a living with this skill. Later, impoverished literati participated in it, and the traditional jokes appeared in the creation developed backwards as the joke said. The content in the book is used to give people a bright side. Only the artist knows the real ups and downs.
