Ask people who know Feng Shui what big water and small water mean? Is there water around the cave?

Big water, small water and even mainstream, shrimp and crab water. It refers to the water in the halls, caves and halls, and there is no place to divide it. Of course, there is almost no room for water to move and exist in the cave. So what you mean by num is actually water in a hole in the sky. If it is far away from the cave inside the dragon and tiger, that is another matter. This is too clever to elaborate.
