Children have many taboos in their daily life. For example, children should not mention the mouse's tail, otherwise they will be unable to read or write well when they grow up; Don't eat chicken feet either, or you can't write well when you grow up; Avoid peeing on the fire, otherwise it will pollute Vulcan, be blamed by Vulcan, and the genitals will be red and swollen; Don't wipe your ass with paper, book paper or manuscript paper after defecation, otherwise it will be disrespectful to Confucius, who will blame you and your academic performance will be bad; Measles or vaccinia can't eat geese for three years, otherwise there will be leprosy symptoms; Don't eat while carrying a bowl, or you will be distracted when you grow up. You can't use plates and saucers to hold meals, which will make the intestines shallower, and when you grow up, your size will become smaller and your mind will become narrower; When lifting chopsticks, don't hold them at the end of chopsticks, saying that the position of holding chopsticks is related to marriage, the low wife is near, the holding is too high or the chopsticks are at the end, and the wife is far away; The bottom of the bowl should be clean: if the rice grains are not clean, you will marry a pockmarked wife in the future; Don't beat the bowl with chopsticks, because you hold the bowl and chopsticks when begging, and beat the edge of the bowl with chopsticks when begging at someone else's door; When using chopsticks, avoid chopsticks of different lengths, otherwise you will cross the bridge by mistake every time you go out when you grow up; Don't swim with chopsticks, that is, you can't make up your mind when you hold food with chopsticks, so you will be careless and unsuccessful when you grow up. Some of these taboos are superstition, and some are an education for children's behavior norms.
