A joke about holding a tree.

Because in the eyes of some ancient people, these practices are very dangerous: in the past, the ancient temples in barren hills were very powerful, and it was easy for one person to be killed when he entered the temple; If two people look into the well at the same time, it is easy for the one behind to push the other person into the well and drown; Three people hold the tree at the same time. If two of them want to murder each other, grab that person's hand and subdue him.
