Degang Guo had a joke. When I was a child, I studied with Yu Qian at school. He put a whistle in my ass. What's the name of crosstalk? thank you

You are not talking about when they go to school, but when they train their disciples. Among them, Sun Yue is a PE teacher, and Teacher Yu likes to eat brown sugar with sesame sauce. Then the whistle was originally from Sun Yue, and I accidentally took it by mistake. ......

The above passage is from the cross talk "The Teacher is Coming" (no matter which version is available), and there is also a new version of "Eating Mooncakes" with this description. You can search Baidu for "the teacher is coming" to listen.
