2. The ancients believed that "the land where cows sleep" was a blessed land for a long time, and they believed that building a cemetery here could make future generations promoted and made a fortune. According to legend, this is related to Tao Kan, the great-grandfather of Tao Yuanming in the Eastern Jin Dynasty. When Tao Kan lost his father and was about to be buried, a cow suddenly disappeared from his family. Tao Kan looked around and met an old man halfway. He told him that if the deceased was buried in that place, future generations would be "very human." Tao Kan buried his father accordingly, and it was fulfilled.
