Yin House Feng Shui: Explain in detail what sand is? -The answer is: The mountain that surrounds and guards the acupoints can be called sand. The mountain on the left is called Qinglongsha, the mountain on the right is called Baihusha, and the mountains in front are called Anshan and Chaoshan. The mountains behind are called Zushan, Mother Mountain, Ghost Mountain and Leshan.
