As for stubbornly implicating your grandfather, we should analyze the problem of time. For example, your grandfather just died and was buried, and your uncle died within a month; Besides, my uncle once attended a funeral. Then you have reason to doubt the relevance of this matter. It is called "rushing brake" in geomantic omen (it seems to be an excessive earthquake, but there is no difference in appearance). It's like lighting a fuse with fire, which has caused shock and injury to people with or without family history. Otherwise, it can never be inferred that it is your grandfather. Your inference does not exist in the actual feng shui case.
