Is the folk geomantic formula scary? Who is the most powerful feng shui master among the people?

I cann't believe I asked some nonsense How many people have you met who are familiar with all folk geomantic formulas? Do you know what Feng Shui is, or folk Feng Shui? There is only one school of geomantic omen, and there is no saying among the people. Sanhe, Sanyuan, Qimen, Kong Xuan, Bazhai and Tongyang are called sects, factions and geomantic learning. This is what you learned. There has never been folk Feng Shui, only what you have learned, whether it is metaphysics or Qi.
