How to put an end to some unreasonable folk customs?

In our country, there are many economies and customs in many areas. With the development of science, many customs belong to feudal superstition. Personally, I think that although many traditional folk customs have been circulated for many years, they must be reasonable. Summing up the current experience and lessons, we have many traditional etiquette and moral concepts that need to be improved, but many traditions are unique cultures and should be preserved.

Folkways Many people in China may have experienced such a thing when they were young, that is, they were often severely warned by the elderly when they were not sensible. Playing an umbrella in the room will not grow up, and many children have experienced it. So, I also think this is a fact. In fact, this is just to scare children. The real reason is that it was also a feudal superstition to attract ghosts with umbrellas in the past. This concept is actually recorded in ancient novels. Ghosts are afraid of the sun, so they hide under umbrellas and walk around. According to this superstition, it has been circulated among the people, but it is not enough to be believed in Feng Shui.

Children who don't shake their legs at will generally like activities. They usually consciously shake their legs when sitting in a chair or in front of a bed eaves. This habit is often criticized. There is a folk saying that men shake poor women's legs, which means they can't shake their legs when they are idle. This will shake away good luck, and this result sounds particularly harmful. This economic custom is also based on science. It's not that serious, but it makes sense. The real reason is that we want to be polite and steady when we pay attention to etiquette and interpersonal communication in society, so the habit of shaking our legs is frivolous, rude and disgusting.

Then we should also improve these traditional bad habits. After all, there must be a legacy of tradition. Although many statements are not feasible, we should live in a scientific way with the development of science.
