What animal is a metaphor for hitting a person when he is down?

It is not that pigs love to fall when they are depressed, but that some proverbs and habits correspond to the zodiac. For example, when they fall, they correspond to pigs. Because falling is harmful, "harm" and "hai" are homophonic, and "hai" symbolizes the "hai pig" in the zodiac, that is to say, the animal zodiac corresponding to this sentence is a pig.

It means that when someone is about to fall into a trap, he is not saving him, but pushing others into the trap. Generally used to describe framing others when they are in danger. This idiom comes from the epitaph of Liu Zihou written by Han Yu in the Tang Dynasty. Words with similar meanings include throwing stones into wells and so on.

Down and out people like to play tricks on others. They always like to make others angry, make a fool of themselves, make people crazy, and sit by and watch each other's jokes. Therefore, most people who fall when they are down are out of playful psychology.

Friends should share weal and woe. If there are people around you who always like to throw stones at you, it's best to stay away from them for three feet, which will only do you harm.
