The underlying color of a market is like a person's nature, which is difficult to change. If it is a liar, the best way to treat him is to ignore him and let him entertain himself and survive on his own. But I know this is obviously impossible. After all, this liar is very good at making a living. He can do magic, acrobatics, sketches, and talk shows. There are always some people who like to watch and listen to him, especially newcomers who have not been deceived by him before.
