Why can't I use a knife on New Year's Day?

This is a taboo in China's traditional New Year custom. It's unlucky to use a knife this year, so you can't use it.

In fact, it is not only the first day of the Lunar New Year, but also the first day to the fifth day. However, due to the development of society, many young people now basically ignore this point and don't move their knives on the first day at most. During the New Year in China, people pay more attention to entertainment and gradually downplay their sense of ceremony. During the New Year in China, there are still many taboos, including not sweeping the floor on the first day of the New Year, not using scissors and kitchen knives, not saying unlucky things such as death, death, rot and bad, and not shaving your head throughout the first month.
