What is the meaning of "water entwining Xuanwu" in Xuankong Feng Shui?

The location of Xuanwu should be based on the mountain. If water surrounds Xuanwu, it means that the water dragon has gone up the mountain, and the owner has lost money. This is generally a bad symbol. It must be oriented with the compass and combined with the three dragons. Judging from the flying situation, if the two stars are sitting together, it is a good thing. It means that Ding and wealth are prosperous, so you need to conduct on-site inspection, and the sitting direction must be clear.
