The house should be narrow at the front and wide at the back, which can hide the wind and accept the air. It is an auspicious feng shui pattern. The front of the dustpan house is wide and the back is as narrow as a coffin, and it is difficult to accumulate wealth because of disasters. Therefore, "the house is dustpan-shaped, and future generations are poor."
The house in Bojikou can be cracked by the town house (lucky one of Five Elements), and the wealth can be replenished by the energy of Five Elements, so as to solve the problem of wide front and narrow back.
