What do superstitions mainly focus on? If it will harm other people's health, I suggest you don't believe it, but if it is a good thing, treat it with a grain of salt. Because many superstitions in China are actually based on the experience of many predecessors regarding changes in the natural environment, but the science was not developed at that time and the explanations were not clear. In fact, just like Feng Shui, many people regard it as superstitious, but in fact it has certain scientific truth.
