Qinglong is in the east, and Long Mai in China extends from west to east. Altai Mountain and Kunlun Mountain are high in the west and low in the east. Therefore, Qinglong was originally in the east, with low mountains and rivers, which meant gathering wealth. The East is originally low, so there can be signs of gathering wealth. But the mountains and rivers hanging in the east mean that it hinders the accumulation of wealth, which is unfavorable.
The west is a white tiger, and the five elements of the white tiger are the main gold. The five elements represent the golden people, and the mirror is prosperous, so the mirror hangs on the west, which hinders wealth, is unfavorable to the world, and competes with others for profit. White tiger stands in the west and houses with mirrors tend to get dirty.
