The triangular roof or sloping roof with a large inclination is called "cold shoulder house", which is a feng shui pattern that is not conducive to wealth accumulation. The sharper the roof, the greater the negative impact. The triangular roof with a large inclination will make the air flow inside and outside the house abnormal; The sloping roof will make the intake of outside air more, and the frequency of the body will be unbalanced. Living under this deformed roof for a long time, it is easy to become neurotic and hysterical, and eventually depression becomes a disease.
The roof is a circular building, which is not suitable for cooperative housing. In ancient times, circular buildings were mostly tombs, mausoleums, Taoist temples, temples and ancestral halls, so they were unlucky.
