Building a house is a taboo in geomantic omen.

1. All places used as slaughterhouses, temples and morgues in history, ancient battlefields, accident-prone areas, strange slopes, ancient tombs, crematoriums, Miao Di, woodlands, ancient roads, ancient rivers, prisons and execution grounds. It should be regarded as an unclean land that has not been resolved by Feng Shui, and it is generally not suitable for living.

2. It is not advisable to choose the chimney, iron tower, upright telephone pole, transformer, straight roof, wall and other evil objects as the base of the house. When planning and arranging these evil things, we should fully consider the feng shui interests of the nearby land and not arrange them at will.
