Which great man's grandfather in China's modern history may have died of geomantic omen instead of normal death?

This is a story about Mao Zedong's childhood, but it's just a rumor.

The story is that when he was a child, he somehow met a very wise Feng Shui master. I remember that Feng Shui master was also famous, but I forgot his name. Then he told Mao Zedong's fortune and gave several numbers, but I also forgot the numbers. It was four. In any case, this is closely related to the turning point of Mao Zedong's life. One year seems to be a year of war. Then it seems to be the story of the ancestral grave. The grave was originally someone else's. Later, when they buried his grandfather, they accidentally buried their neighbor. In a word, it is a village. It is said that the official also said that the grave of a family with more money was accidentally dug, and then his grandfather's grave was buried, and then that family began to be lonely. Later, Mao Zedong's life became a legend ... This story is too long for me to remember clearly. But I've never heard of unnatural death. Maybe what the tour guide was trying to say at that time was that the Feng Shui master was very good. After Mao Zedong, he went to Lingyin Temple every year. Feng Shui master is also related to Lingyin Temple. Probably, I can't remember the details ... hehe.

Few people know this story, and I don't know whether it belongs to unofficial history. You can visit unofficial history if you are interested.

I hope I can help you adopt praise ~ I don't understand the question, thank you ~
