What about moving the grave? I found that grandpa's coffin was wrapped in more than half of the termite nest. Is it a feng shui harmony? Ask others for advice.

It is a disaster to find termites invading the coffin in the grave! Must move the grave. The second time you move the grave to pick up bones, you must wash the bones and clean up the attached termites thoroughly.

"A thousand-mile cave collapses in an ant nest", and termites in geomantic omen are difficult to control, which is quite harmful and difficult to put out. Similarly, termites breed quickly, dig deep, eat coffin bones, frighten ghosts and harm future generations. There is a condition that "termite invasion" must be moved to the grave of the yin house.
