Does Feng Shui really exist? Douban

I have read several related books. There is no "learning" except nonsense. That is, "wind, heat, dampness and cold" as well as lighting, surrounding vegetation, etc. Building a house on a wind duct must withstand all kinds of winds in the four seasons. Building a house on the southern slope of a mountain col will inevitably lead to high temperatures in summer. Building a house on wetland means it will be wet and cold all year round. If the buildings are densely packed, they must be facing upwind for ventilation and south facing the sun. What water, fire, wood, metal and earth seems far-fetched. It's just based on the money in hand, choosing the most suitable place for you to live, the indoor ventilation and light transmission, and the indoor structure and furnishings that look pleasing to the eye, that's all.
