The first reason is that girls pay great attention to their body shape. Basically every girl wants to have a slim figure. After nailing the tongue nail on her tongue, she couldn't swallow it at all when she was eating, let alone wolfing it down. She can't control her appetite by her own consciousness, but by her physical condition to achieve the goal of dieting and eating less. In addition, you must rinse your mouth every time you finish eating, otherwise you will leave something unclean on your tongue, causing symptoms such as oral ulcers. These habits must be done and will become one of their own habits. Even if you eat a biscuit, you should rinse your mouth, so as to achieve a very clean habit.
The second reason is that those who nail tongues think it's cool to nail tongues. Nowadays, teenagers are very curious, and they have to try anything strange, especially out of their love of beauty, and they have to pursue these strange things to do.
Of course, there is also the last situation, that is, children who are in adolescence will have some rebellious psychology because of family dissatisfaction or dislike of society. They will do some self-abuse, and some people will nail their tongues to show their dissatisfaction with their families or society.
Nailing your tongue is bad behavior. Bian Xiao suggested here that everyone should not do something strange. Everything must have a scale, and you can't pursue the aesthetic effect too much and ignore your health. All right, that's it. Thank you for watching. Give Xu Daqiang some attention and love.
