Ask for a short story or joke or game that can enliven the atmosphere.

A turtle crossed the river to attend the forest convention. There is a river to cross on the way. This turtle can't use any tools or animals to help. How did it get there?

Of course, the answer is not dizzy. It is said that the tortoise thought for a long time and didn't come up with it. That is to say, the people who are thinking about the answer are turtles, hehe.
