Behind my house is a mountain. There are many graves on the mountain, which are equivalent to mass graves. What is this feng shui? I feel that the yin behind my house is so heavy at night.

You have lived here for more than ten years. As long as you feel normal and good in all aspects, this feng shui is good feng shui. As long as you are not burying a new grave, don't think about him. Now, there are ancient tombs in the underground of many residential areas where people once lived. In other words, if the graves are removed, who will remember them in 20 years?
