First of all, it is true that many feudal superstitions in ancient China were wrong, but they can't all be said to be wrong, especially gossip and geomantic omen, which also played a great role in some modern movies, such as ghost blowing lights, detective in Chinatown, and professional novels. These are all handed down slowly by our ancestors, which are profound and difficult to understand.
It is true that we are now in an era of pursuing science, but many things, even our current science, are difficult to explain and find the root of the things involved, such as fate. I think a lot of things would not have been circulated for so many years if they were fake. After all, time is used to test the existence of everything. People will naturally think that they are wrong and will gradually abandon them, but these geomantic omen are different from gossip.
It has existed for such a long time, so I think it has its own reasons, especially businessmen and the like, who care about their wealth very much, and people with high academic qualifications study culture and the like, which is also a research direction. Anyway, it is the traditional culture of China, which is really profound. You can think about it.
