Yang Wu believes that no matter in the mountains, hills and plains, there will be great officials, and there will be great officials' tombs in almost any area, with different shapes and sizes, but they all have one thing in common: the pulse is true, the pulse is prosperous, and the mountains and rivers intersect. Burying ancestors in the land with excellent feng shui will definitely bring good luck to future generations. On the other hand, feng shui is not good, and everything goes wrong for future generations. What's worse, bad luck continues and families break up.
