Some problems about geomantic omen
First of all, the purpose of Feng Shui Feng Shui is to raise people. Feng Shui is not only used for building houses, mining and treasure hunting in tombs. To put it bluntly, feng shui is actually to find a more pleasant environment to raise people, and people will naturally live longer and healthier. This is for the living. Why should the dead look for a cemetery with good feng shui? Or to feed people, that is, the descendants of Zefu. As you said, people in China pay great attention to the preservation of corpses. Before the rise of geomantic omen, there were traditions to prevent corpses from rotting, such as putting plant ash in coffins, making coffins out of fine wood, coating thick paint on the outside of coffins, and even coating the corpses with cinnabar or gold plating, all in order to prevent China people from thinking that human corpses are evidence of human existence in the world. It is also the key for the dead ancestors to contact the world. Then the immortal of China said that after death, someone will ascend to heaven, and keeping the body is a necessary condition for immortality. This is a saying that all China people attach great importance to preserving their bodies. Now back to your question, Feng Shui is actually looking for a place to help store the body. If you pay attention, you will find that Mr. Feng Shui never chooses terrain. Place the grave by the river, under the hillside or by the roadside, because these places will destroy the body. In other words, if you imagine that the body of your ancestors was washed away by the river, torn by wild dogs, or the grave was built on the side of the road, you will fidget all day, and your health will be greatly reduced. Are you talking about the descendants of Zefu?
