Yao Xiaoguang assisted the prince to ascend to the throne and built the imperial tomb in Changping.
The prince asked him if Changping could bury Fengzi and his grandson.
Yao replied that it could not be buried, because the Zhu family's children and grandchildren would be buried all the way to Shanxi and Henan.
The prince was very happy and buried all the way to Shanxi and Henan. . . That can't sit for thousands of years!
Later, Chongzhen was buried in Siling. The somebody else wanted to think, four spirits in the west of Crouching Tiger Mountain, Zhaoling Henan!
So Yao is right, and there is a story about where Zhu Jiatian was buried.
