What is the difference between the geomantic power of cremation and burial?

1: Cremation is not as powerful as burial. In today's society, the cremation system is implemented, and the deceased is buried after cremation, so the power of Feng Shui is somewhat discounted, because after cremation, the five elements are only one and cannot be buried, and the five elements are irreconcilable with Yin and Yang. The power of geomantic omen can't be fully exerted by soil alone, which is why we can talk about geomantic omen with evil spirits before cremation, which can benefit the next generation.
