What is the meaning of the four waters returning to the hall in Feng Shui? The four waters in the geomantic omen of the Yin House return to the hall, please give me some advice.

In feng shui, "four waters return to the hall" generally refers to the yangzhai. There is a courtyard (common in ancient buildings) in the middle palace of the house, and there is a quadrangular pool on the courtyard. Whenever it rains, rain flows into the yard from four sinks like four hoses. This is "four waters return to the hall". Feng shui means gathering the wealth of the world.
