What do you mean by sticking out your tongue?
What psychological expression is tongue sticking out? People can't use their hands accurately and flexibly in childhood. When children are fed food they don't like, they will instinctively squeeze it out with their tongues.
When children are older and don't like someone, they will stick out their tongues and make faces at someone. At this point, sticking out your tongue is also expressing the meaning of rejection and resistance! When I grow up, although I "quit" making faces, when I am bored, I will still say something perfunctory, then shrug my shoulders, spit out my tongue, or raise my head and stretch my chin.
In short, when we encounter troubles or are forced to chat with people we don't like, we often make such actions unconsciously. In addition, when doing some fine work, some people will stick out their tongues with their mouths open all the time. This action is an evidence that he is very devoted, so concentrated that he even forgets to put his tongue back in his mouth.
A big and long tongue can make you rich: a person's tongue looks big and long, so it is cunning and selfish, but he will go forward for his own purposes and lay a solid psychological foundation for future wealth accumulation.
