How to understand the cave's "shallow burial and deep burial"?

The shallowness and depth of Yinzhai Fengshui is about the shallowness and depth of Fengshui. Those who are shallow and deep can be said to be accurate. If the shallowness and depth are appropriate, the feng shui will be formed by itself, so those who divine the earth must use shallowness and depth as the criterion. If the burial is shallow and deep, the Qi will pass from above; if the burial is deep and shallow, the Qi will pass from below. This is why even though you can get auspicious places, it doesn't work. Generally speaking, first check the yin and yang of the pulse, and then look at the subordinates of the four mountains. If the pulse enters the head and is strong, making a concave point, and the exit is round, this means that the pulse is floating and the point is yang, so it should be shallow. When Lailong enters, the head is weak, the acupoint is convex, and the exit is sharp. The pulse is deep and the acupoint is yin, so it should be deep. Therefore, there is a saying that the shallow and deep can be multiplied, and Feng Shui is self-contained. The methods of shallow and deep are changeable, but the principle is nothing more than this. It is important to identify the clear boundary between the yin and yang shrimps at the beginning. If it is deep and shallow, or shallow and deep, if it is worse than within a short distance, it will turn out to be good luck instead of bad luck. The scripture says: The good place is good for burial but bad for burial. It is the same as the abandoned corpse.
