Sorry, I dug up the eel when my family moved the grave.

There is something wrong with feng shui acupoints. Who found it? Do you have a grudge against your family? I feel that Mr. Feng Shui is playing you. There are problems with both. It must be intentional. Generally speaking, buried in ordinary places or caves, there will be no blackening of bones; Besides, there are eels? There must be something wrong with that cave. It's vicious to let fish and shrimp eat it. Even if they die, they won't be allowed to live. Your family doesn't seem to be doing very well. Either sick or unlucky.
