Introduction to Zhu Xi's ancestral tomb: is the tomb of Zhu Xi's grandmother. Zhu Xi's great-grandfather asked a famous Feng Shui master at that time to observe the image. The master discovered that Wengong Mountain happened to be on the dragon's head. At that time, there happened to be a post road passing along the mountain one day, so some people said it was a dragon vein. Later, Zhu Xi's grandmother was buried on the mountain. Some people said that the descendants of the Zhu family would definitely produce "adults", and indeed there was Zhu Xi.
