What happens when tung oil is poured into the grave?

Tung oil poured into the grave, tung oil disappeared, and the grave remained. Nothing should change except drilling a gas hole. But why are there graves filled with tung oil?

Lao: First, ward off evil spirits. Second, break the feng shui. To ward off evil spirits means that the dead in the grave are buried in the demon land and become evil spirits. Evil spirits can be scalded to death with high-temperature tung oil. Breaking feng shui is a good place and a place where dragons live. I am afraid of high temperature tung oil, and I will die as soon as I get hot.

When the demon was broken, it was said that someone had used it, and the effect was average. "No demon, fake demon" can be effective. "True demon", no matter how to use it, is "evil" anyway. Someone else is doing it. What's the effect? There is no conclusion. It's as mysterious as being a thief to do so much work with a few hundred dollars of oil. Is it worth it?

Is this the only stupid way to break the feng shui, and there is no other bad way? People who do it should read more feng shui books, and it is best not to use stupid methods!
