According to some geomantic views, ancestral graves are mostly flooded because of the evil style of writing or the evil style of writing, so you can't see clearly when standing. Under such circumstances, ethnic minorities may easily get sick, including some lower limb diseases, lumbar nephropathy, rheumatic diseases and even serious accidents.
Although these views are unscientific, these adverse effects are not groundless. If the coffin is soaked in water when moving the grave, it is suggested to find a professional grave moving company or feng shui master to deal with it to ensure the safety and smoothness of the grave moving process.
