Is it better to build the tomb on the mountain or under the mountain?

Generally speaking, it is appropriate to build a tomb on a mountain. Building a grave pays attention to "looking forward and leaning back", while Feng Shui often says that "getting water is the top, hiding wind is the bottom". The tomb is built on the mountain, and the terrain is superior to that of the mountain. There is often water under the mountain, especially in rainy days, and the water rushes down from a height, which is very taboo. Choose a flat land with wide terrain on the mountain, with water on the front and sloping ridges or both sides.
