First, Yong Zhengdi thinks that the feng shui of the mausoleum is better.
There were 13 emperors in Qing dynasty. Except Yong Zhengdi, the tombs of the other 12 emperors are in the Qing Dongling. But in Yong Zhengdi, the situation is reversed.
Because Yong Zhengdi found that the scenery of the Qing Xiling Mausoleum was very good during his tour, and Yong Zhengdi was superstitious, he thought it would be a good thing for future generations to build a mausoleum there first, so he built the Qing Xiling Mausoleum according to his own ideas.
Although Yong Zhengdi was buried in the Qing Xiling Mausoleum after his death, his practice gave Emperor Qianlong a big problem. Because Emperor Qianlong didn't want to build his mausoleum in the Qing Xiling, but if so, Emperor Qianlong would probably be branded as unfilial. Later, after careful consideration, Emperor Qianlong built his mausoleum in the Qing Dongling Mausoleum.
Second, no one dares to raise an objection.
The reason why Yong Zhengdi dared to go against orthodoxy and build his own mausoleum to the Qing Xiling Mausoleum was mainly because when Yong Zhengdi was in power, he was the supreme ruler of the whole dynasty, and no one dared to raise any objection.
Third, what other sayings are there in history?
Historians have other views on Yong Zhengdi's practice. It is believed that Yong Zhengdi is not in the Dongling Mausoleum of Qing Dynasty, but in the Xiling Mausoleum of Qing Dynasty, mainly because the cause of death of Emperor Kangxi is unknown.
It is speculated that Emperor Kangxi was killed by Yong Zhengdi, and Yong Zhengdi was afraid to see his father, so he built a mausoleum in the Qing Xiling. Although this statement is only a guess of later generations, there are still many people discussing this issue.
Summary: The reason why Yong Zhengdi built his mausoleum in the Qing Xiling Mausoleum is mainly because he thinks that the Feng Shui of the Qing Xiling Mausoleum is better.
