"Qinglong" and "White Tiger" are ancient beasts, Qinglong represents the East and White Tiger represents the West, so in the geomantic treasure house where you live, Qinglong represents the West of the house and White Tiger represents the East. "White tiger covers green dragon" means that the east side of the house is higher than the west side, but the green dragon in the west side can never be higher than the white tiger. In fact, this is a feng shui model, and the house in the west is shorter, otherwise it may be bad for the neighbors in the east.

Others say it has something to do with sunshine. Most ancient houses were made of wood with paper windows, but they were easy to catch fire. In order to reduce direct sunlight, people build houses in the west shorter, and let the sun shine directly on houses in the east at sunset. This is because people subconsciously think that after a day's irradiation, the sunset is very hot and easy to cause fire, while the house in the east is a little far away and is not afraid of being set on fire.
