Wang Xingren is a kind of network language, which imagines dogs as aliens from outer space, defrauds people's trust with their lovely appearance, and then unexpectedly occupies the bone resources of the earth.

Wang Xingren's old enemy is a cat. Cats mean that cats should come from distant outer space, because their lovely appearance has won the trust of human beings and become a few friends who communicate with human beings on an equal footing. Cats are different from Wang Xingren. Cats are self-domesticated animals. The reason why Wang Xingren can adapt to human life at first is that their social behavior matches human beings in many ways. Cats are different from humans. They are solitary hunters with fixed territory, and most of them are active at night. However, it was their hunting behavior that first brought cats into contact with human environment, and their strong instinct to protect territory drove them to appear in the same place.
