When 坟地 was built in ancient China

it had relative good fengshui. It is still common practice to check 坟地 fengshui in modern China? so It is hard to argue the bad fengshui near tomb site (坟地).

I looked at website regarding this issue. I think a good point is in ancient time, 坟地 was most likely the source of water pollution and disease. But in modern days, water is more likely provided by utility companies.
