In the previous feudal superstition era, people believed in ghosts, fearing that they had accidentally offended the dead, and the dead would turn into ghosts to get back at themselves. Therefore, feng shui masters can communicate with the living and change the date of breaking ground, but it is different to show it to the yin house. In addition, the dead people in the yin house and their descendants have an influence on the geomantic omen in the yin house, while the living people in the yang house have an influence on the geomantic omen in the yang house. In addition, the level of Feng Shui master will also affect the effect of Yin House Feng Shui. Some feng shui masters try their best to cheat the owner of Yin Zhai Feng Shui for immediate benefits, which will lead to the failure of watching Yin Zhai Feng Shui.
Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
