I went back to my hometown to sweep the grave the day before yesterday and found a ditch dug behind the grave. What do you say about this? First of all, this ditch is really difficult to dig. It is easy to accumulate water on rainy days, so pour it into the tomb. It is easy to cause the tomb to collapse. Again, feng shui is not good. What we are talking about is that the grave is rising and the descendants are heroic. He is digging a ditch now. It's not good for the younger generation either. I hope I can help you.
