Many people were buried with Princess Yu Sheng. One of the reasons was that the King of Wu didn't want his daughter to feel lonely. The King of Wu loved his little daughter Princess Yu Sheng very much, so he gave her the delicious fish he had tasted and wanted her to try it, but Princess Yu Sheng was very angry. She thinks it was left by her father. The king of Wu saw this scene and thought it would be good to calm his daughter down. Unexpectedly, Princess Yu Sheng directly went back to her room and committed suicide. The king of Wu was very sad. He was afraid that his daughter would feel lonely, so many onlookers buried her.
In addition to the prince of Wu, there are bystanders who are so fascinated that they always follow the coffin, which leads to the tragedy. At that time, Princess Yu Sheng's funeral was very spectacular and grand, and there were people dancing. Ordinary people have never seen such a scene, so they followed and walked into the grave of Princess Yu Sheng unconsciously. Later, at the command, the gate was closed, and the people watching the scene realized the seriousness of the problem, but it was too late to stay inside.
To sum up, these are the reasons why many people who watched Princess Yu Sheng's funeral became funerary objects. First of all, because the prince of Wu loves his daughter too much to bear to see her lonely, he brought many innocent people to accompany her. Secondly, because the people were so fascinated by the excitement, they didn't even realize that they had entered the mausoleum, and finally they were suffocated alive and became the funerary objects of the princess.
