Siheyuan should be narrow at the front and wide at the back, which can hide the wind and accept the air. This is Geely's feng shui pattern. The dustpan-shaped courtyard is as wide as a coffin in the front and as narrow as a coffin in the back. Because of the disaster, there is a "dustpan-shaped courtyard, and future generations are poor."
The dustpan-style courtyard can be cracked by the town house, and the five elements of energy can be used to supplement wealth and solve the problem of wide front and narrow back.
