Why do people who go to Deyun Society to listen to cross talk always give presents to the actors on the stage?

It's not a fish, it's "alas", which is quite interesting. At first, it was a way of clapping in Beijing opera, that is, "Yes!" When the audience's mood is no longer satisfied, when Lao Guo is not popular, some old audiences bring this applause into the crosstalk theater. As a result, some new audiences didn't know the truth and shouted along. As a result, it turned out to be "Xu". Now, listen to the earlier recording, and you can still hear "Xu" Later, in the performance, the audience began to learn to shout instead of promise. Very interesting.
