Why did Han Xin bury his mother alive?

Han Xin has a neighbor, an old man, who likes Feng Shui very much. One day, the old man said to Han Xin that our back mountain is a treasure trove of geomantic omen. This is the legendary Long Mai. In the future, if people are buried alive, there will be a son of heaven, and if they are buried alive, there will be a scorpion. Then one day, Han Xin asked his mother to come to the back hill and said there was a good place. Han Xin's mother is blind. She followed Han Xin to the back hill.

Han Xin watched his mother go ahead, so he took out a wooden stick prepared in advance and knocked her out with a stick. Then his mother was buried alive in what was then Long Mai. Later, Han Xin went to war with Liu Bang, commanding thousands of troops and becoming a famous soldier in the Han Dynasty. Unfortunately, Han Xin was killed by Lv Hou after all. Because the old man who can see Feng Shui knows that Han Xin buried his mother alive, he shook his head and said that no matter how good Feng Shui is, geographers can't get justice, and justice can't bear it. After all, there will be no good result. It's a little sad to think about it. The prince and the prince are not as good as their mothers.
