Most of the concubines who were martyred had no children, and they would be arranged to be buried if they were helpless. Except for a few concubines, because her son was made the next emperor, but the son was still young, and the emperor was afraid that the power would fall into the hands of the concubine, so he specified that a certain concubine would accompany the burial.
Archaeological experts have found many burial pits, in which a large number of bones are placed, and the death is quite hideous. Especially when the ancient Chinese emperor died, the legs of the martyred concubines were greatly separated.
In fact, it can be seen from their deaths, because they were not willing to be buried, and they all struggled fiercely before being buried in the mausoleum, and even had their legs forcibly broken. There are even some who are stuffed into coffins and mausoleums while sleeping, and after losing oxygen, they struggle desperately, so the death is horrific. The horrific deaths of these concubines show the pain and struggle they suffered during the burial process, resulting in the tragic state of spreading their legs.
There is such a clip in the movie "The Legend of the Demon Cat", Yang Yuhuan, who was deceived into drinking poisoned wine and thought he would die, woke up in the coffin, and then struggled and wailed in the small sarcophagus, but no one could save her, people opened her coffin, and there were traces of fingernails scraping inside, mottled with blood, this kind of struggle that slowly felt that her life was lost and she was powerless was much more cruel than sudden death.
