What is the meaning of "starting sand"?

The sand on the feng shui, also known as Xiaguan, lower arm. Regardless of the east, the west, the north, and the south, all the water outlets are collectively referred to as the starter. Liao Gong once said: "Ask you how rich you are, and you will get together with the sand; ask how poor you are, and the sand will run smoothly." Where there is sand for the start, there is a knot. As long as you can ride a mountain and cross the mountain, it is Jidi. If the water in front of the acupoint returns to the left, then the left is the start; the water in front of the acupoint returns to the right, and the right is the start.

If you want a mountain against the water on your left arm to be longer than the mountain on the right, and hold the mountain and water on the right; if you want a mountain against the water on your right arm to be longer than the left hand, and hold the mountain and water on the left, this is called Niguan, and the Lord makes money. If the lower hand mountain shrinks, and the upper hand mountain is not enough, it becomes a fake acupuncture point. Closer overlap of the hands, the bigger the result. If you are open, you don't need to find the ground.
