It is said that Kangxi sent a mausoleum minister to Dongling to find the location of the mausoleum for himself. Later, the minister found that the site was a rare "Feng Shui" treasure. The mountains here are continuous, the vegetation is lush, and the pine and cypress are evergreen, which is a good place to build a mausoleum. However, everything is difficult, and the site selection is flawed from the beginning. The defect is that there is a deep pool in the center of the designated area of the cemetery. Kangxi stayed here all night and decided to choose this place as the mausoleum. Due to the low terrain and various factors, the later tombs were flooded.
