Why did Dr. and Mrs. Li's formula crosstalk cause an uproar?

Degang Guo was right to give them up. Degang Guo said that people who have studied crosstalk for more than 20 years since childhood have to undergo strict selection and evaluation at this stage. Why don't you two learn crosstalk all day? I want you to be unfair to those who cross talk from primary school! More importantly, they can attract so much attention because they also challenged Degang Guo, who is now the most popular crosstalk performer. And the crosstalk is formulated. There is no denying that there is something psychological in cross talk. But you can't just talk about a few books. This is an art that can only be performed on the stage after a long period of systematic training! No, just to be famous denies the achievements of so many famous crosstalk artists.
