The ancestral graves at home were dug at night, which ruined the reputation of Feng Shui. Killing father and wife had nothing against anyone. Why? Where does this man live?

As you said ... there is no hatred for anyone who kills his father and takes his wife ... it is impossible to dig up the treasure ... The grave robbers know whether the year of the tomb is an ancient tomb. ..

Then there are several possibilities. ...

A ... your ancestral grave ... blocked people's feng shui ... for example, good luck was blocked by your family. ..

Second, maybe you offended someone, but you don't know, you ruined your feng shui and wanted to go to your house to eliminate the disaster. ..

Your family is prosperous and powerful. The wicked are jealous .. (or it may be your business rival ... who is doing this ...)

Rebuilding ... setting up a geomantic omen bureau in the tomb ... promoting auspiciousness, resolving the disadvantages brought by the broken tomb ... continuing luck and promoting good luck.
