After the establishment of Nurhachi regime, they also built tombs for their ancestors, so these three imperial tombs are collectively called "Three Tombs Outside the Commissioner". After Shunzhi entered the customs, in order to meet the needs of governing the country, it was obviously inappropriate to build an imperial tomb outside the customs. Before the Qing Dynasty, all dynasties were "wooden" and "children were buried with their parents and inherited by their ancestors". I have to say that the emperors of the Qing Dynasty were also buried together. But after Yongzheng succeeded to the throne, many people questioned the origin of the throne. He didn't want to bury it too close to his father Emperor Kangxi.
China people's ancestor worship culture makes everyone in China taboo to destroy their ancestors' graves. The ancients believed that the geomantic omen in ancestral graves determined the success of future generations. If in ancient times, a person suddenly got lucky, others would say that "the ancestral grave was smoked." The feudal imperial system based on "family under heaven" linked the graveyard of the emperor's ancestors with the long-term stability of the dynasty.
Because there are many valuable funerary objects in the grave, and the address cannot be hidden, it is inevitable that there will be robbers who are not afraid of death. In order to avoid being interrupted by ancestors, all previous dynasties sent troops to protect tombs, and the Qing Dynasty was no exception. In the Qing dynasty, the people who protected the tombs were all children of the Eight Banners heroes, and their sons were passed down from generation to generation near the tombs.
After more than 200 years of reproduction, some villages have formed near Huangling. These villagers are all descendants of the Eight Banners. Because generations have lived here, they also have a special feeling for the grave. Even after the demise of the Qing dynasty, they will do their best. For example, explaining some obligations to tourists and cleaning up the garbage that tourists can leave behind are not "serious protection".
