How to explain that China people generally believe in Feng Shui theory and five lines of gossip?

Geomantic omen theory and five lines of gossip were formed by the precipitation of ancient wisdom for thousands of years. They are scientific and mythical (meaning that half of them have scientific basis, and the other half are just the beautiful yearning of the ancients). Feng shui can also be said to be a custom. This custom has existed for so long that many people naturally believe it. Until today, some research results of ancient geomantic gossip can not be scientifically explained.
