What are Hanshan and Chaoshan in geomantic terminology?

Case Mountain, also known as Sha Ying, refers to the mountain between Yaodong Mountain and Chaoshan Mountain, that is, the part of the slope closest to Yaodong Mountain and extending slightly higher than Tangming Mountain. Those far away from the mountain are all facing the mountain. The petty bureau case is close to the mountain, and the case is a hundred steps; The mountains of the Atmospheric Administration are far away, which can be several kilometers, ten kilometers or even dozens of kilometers. If the nearest mountain to Cave Mountain is more than 20 kilometers, there are more than 25 kilometers, more than 30 kilometers and more than 40 kilometers. And the farther the distance, the higher the mountain, which is called overlapping mountain. Compared with the mountains of 25 km, 30 km and 40 km, the mountain 20 km upward is the closest to the cave mountain. So the mountain 20 kilometers up is called Case Mountain. The mountains outside the case mountain, that is, the mountains of 25 km, 30 km and 40 km, are farther than the mountains of 20 km upward. So the mountains 25 kilometers, 30 kilometers and 40 kilometers away are all facing the mountains.
