In fact, there are many exquisite chopsticks. When I was a child, my family taught us not to knock on the bowl with chopsticks. This behavior is very bad, because in ancient times, beggars could knock on bowls. Also, when eating, we can't put chopsticks in a bowl vertically, which is also taboo for old people, because we only do this when we sacrifice, and such behavior can't be done at the dinner table. These pressures are of great concern to the elderly.
Most of the dining tables we eat now are round tables, but in the past, as we all know, most of them are square tables, and usually eight people sit on them. But if there are six people sitting at a table, you should pay attention. Don't be a turtle seat. If this is the tortoise seat, we all know that the tortoise has a long life, but if it is used to praise people, it is very inappropriate, that is, swearing, and sitting like this is also disrespectful to the owner.
Three long and two short: this refers to putting chopsticks on tables with uneven lengths before or during meals. This is unlucky. Usually we call it "three long and two short". It means "death". Because people in China used to think that people should be put into coffins after death, and when people put them in, the coffins are made up of two short boards, with three long boards at the bottom of both sides, and the coffins made of five boards together are just unlucky.
The pin will make a sound: this practice is also unacceptable. The practice is to put one end of chopsticks in your mouth, carry it with your mouth, and hiss from time to time. This kind of behavior is considered a despicable trick. Because it is impolite to eat chopsticks with your mouth, and it is even more annoying when accompanied by sound. Therefore, this practice is generally considered to be the lack of family education and is not allowed.
