Can changing the geomantic omen of the Yin House definitely change the fate?

No, feng shui is in power, and power is not immutable. When the environment changes, the motivation will naturally change. Let's just say there can't be a perfect ghost house. In China, there have been countless emperors and princes for 5,000 years, and countless talented people have never seen anyone really find a good position, but in theory, Feng Shui can really affect people's fate, but more needs to be done by themselves.
