In the temple, a monk is telling a story to a young monk. He told a story about a mountain and a temple where a monk was telling a story to another monk. What's behind it?

In fact, this was a cold joke in the 1970s and 1980s, and it was very famous at that time. That's exactly what it says. Once upon a time, there was a temple on the mountain. There is an old monk in the temple. The old monk said there was a temple on the mountain, and there was a little monk in the temple. Then the little monk said, anyway, it is a good medicine to deal with the story addiction of children at night. As long as the adults say this, the children will say, I have been listening for a long time, and the endless story with no ending is not good. However, there is a similar story. Once upon a time, there was a hole in the corner of the warehouse. When the mouse knew it, it sneaked in, so this one ate that one and that one ate this one. Anyway, it is endless. Will anyone eat until they die? Just say no, eat this, eat that, eat that, eat another one ... it's endless anyway.
