What feng shui is there in Qing Xiling?

According to the principle of choosing geomantic omen, Dongling was first chosen as the tomb of the Qing Dynasty, so both Shunzhi and Kangxi were buried in Dongling. When Yongzheng ascended the throne, he chose a mausoleum for himself. He found that all the places with good feng shui in Dongling were occupied by his grandfather and father, so he chose Xiling to sit in his mausoleum. When Qianlong ascended the throne, he originally hoped to be buried by his father, but he was afraid that all future heirs would be buried by his father according to the custom.

In this case, Dongling was abandoned, so that the incense in Dongling was not called Xiling, so Qianlong made a rule that the father and son would be buried separately from generation to generation, and the grandson and grandfather would be buried separately, so that this problem could be avoided. It's just that when Emperor Daoguang wanted to bury his queen together, he didn't bury Grandpa Sui. Later, for various reasons, he followed the rules of his ancestors.
