Q: There is one thing, that is, when an elder's grave is to be moved and buried! If the bones of the elders in the coffin are taken out and emptied

It's better not to do this. Moving ancestral graves can be big or small. It will cause bad health to future generations and seriously affect their prosperity. There is no need to move the ancestral graves. Never! Never! If you have to move, you'd better find a reliable teacher of Yin and Yang, or Mr. Feng Shui to find a good place to choose an auspicious day before breaking ground. Find Mr. Feng Shui and ask him to tell the truth and not be stingy. Don't be careless, be careful.
