Choose a cemetery environment with a big back and a mountain behind it. It's called Parents Mountain. The water potential and sound level around rural graves will have an impact on graves. Generally, noisy sounds will not only affect the rest of ancestors, but also lead to the confusion of the gas field around the tomb, which will have a bad influence on future generations. And the direction of water determines many aspects. If the water in the grave reaches the back of the grave, then later men will have more money, and women will cheat and lose their homes. Water comes out from behind the grave, and men and women lose money, leading prostitution. Solemnly declare: this answer is for reference only, please don't be blindly superstitious.
