Is it recorded in the ancient book Yijing? Dogs can't last eight years, and chickens can't last six years? Because chickens generally live for about 6 years, but if they exceed this limit, they will undoubtedly become monsters and lead to chaos in the world. In fact, this sentence is more related to feudal factors, but in this society, people usually don't keep chickens for a long time, unless they are hens that can lay eggs, but they will usually be slaughtered in a few years, which may be the same reason.
For what? No more than eight dogs? In fact, the most important thing is a short story recorded in Yi Yao, which makes people believe that dogs will become demons after more than 8 years. Once upon a time, a landlord kept a white dog. It can be said that he basically carries dogs everywhere. Later, the landlord died because of physical problems, and the family held a funeral for him, but he didn't expect the dog to disappear after the funeral, but everyone was in a heavy mood at that time. So, nobody cares where the dog went, but a year later, the landlord suddenly came back. He also said that a Taoist priest brought him back to the sun. People believed him when they saw that his behavior was no different from before. But they didn't expect that once the landlord drank too much and slept in a chair and suddenly showed his true colors, so people knew that the dog had become a demon.
In fact, there are many short stories in life, but more of them are full of feudal superstitions. Because of the backward thinking, we will firmly believe in these legends of ghosts and gods, which can only be said to be caused by the ignorance of the times.
