Mr. feng shui

Nonsense, you are not your ancestor three generations ago. You also believe such a "master". You don't have to worship a good mountain correctly. If your ancestor's mountain is good, even if you don't worship him for ten or twenty years, it's ok. We usually cherish our ancestors when we worship them. The second is to see if the ancestral graves have changed, such as the changes in the mountains after the earthquake. That's all that matters.
