When using chopsticks, China people like to show themselves, even before or during meals. Chopsticks should not be staggered on the table, because it represents "three long and two short". In the past, three long and two short pieces of wood were only used for coffins. So it also means bad luck, so when using chopsticks, it is forbidden to do anything wrong.
Don't be a fairy guide. The so-called fairy guide means that the posture of chopsticks is incorrect. If you use your thumb and middle finger, ring finger and little finger to hold chopsticks, your index finger sticks out. This is called swearing in the countryside. This means that when you eat, you blame others with your fingers, just as you hold a grudge against others. This kind of person is easy to provoke right and wrong, and it is easy to meet villains in the workplace. You must be careful, and you'd better correct the posture of holding chopsticks.
