Is "Feng Shui" true or false?

In modern times, many half-baked Mr. Feng Shui exaggerates the problem of Feng Shui for his own benefit and tells you something out of thin air, which makes people feel that Feng Shui is not credible. From the perspective of ancient geomantic omen, it is very scientific, such as 1, which requires a strong wind to gather gas, mainly to keep warm after staying. 2. The background is actually a ridge, not a raised tile shape. Why? There is no danger of water flushing the house on the roof, and it is not safe to flush the house with water on the raised tile. 3. There is a green dragon on the left and a white tiger on the right. But also for the wind and warmth. 4. The front is wide and flat, which is easy to pass and not dangerous. So, when it was later mythologized, it gradually became untrustworthy. So we can't completely deny it, and we can't blindly believe it.
