What is the mountain in Feng Shui?

"Hanshan", also known as Sha Ying, refers to the mountain (sand) between Cave Mountain and Chaoshan Mountain in Feng Shui Bureau. The ancients sat in the hall, and in order to have a rest, they had to put a few cases in front of them. For an air pocket in a Feng Shui Bureau, "An Shan" is just like the previous cases, which is the origin of the title "An Shan".

The function of the "mountain" is to make the lingering in front of the (gas) point more thorough, help to gather vitality, make it difficult for the strong gas to dissipate, and increase the respect of people living there. Xu Shanji mentioned in "What the Son of Man Should Know: Shalu": "The mountain in front of the cave is near and small, so ... it is like the meaning of the law according to several situations. If there is a mountain, it will be densely packed in front of the cave, and there will be no air. "
