This is a famous saying of Quan Xiangyu culture in Sui Dynasty, which is about what he said after he forced the palace to kill Yang Di and slept with Queen Yang Guang. Yu Wenhuaji was a famous traitor and power figure in history, and he almost mastered all internal power in the Sui Dynasty (the external power and responsibility were in the hands of some generals of Zhuguo). It can be said that gaining such authority is almost entirely due to Yang Guang's getting less attention and getting carried away in the middle and late period, and Yu Wenhuaji's catering to Yang Guang's psychology, so he gradually mastered the real power.
Because he was with you all day and served the pleasure-seeking emperor all the year round, Yu Wenhuaji was greatly influenced by Yang Guang when he gradually mastered the power of the Sui Dynasty. He sneered at Yang Guang's concept of enjoyment from secretly to colluding with it, and finally lost his own principles and began to earnestly hope to become a person like Yang Guang.
When the Great Sui Dynasty was about to collapse, Yu Wenhuaji led troops into the palace and killed Yang Guang, and had sex with Yang Guang's queen. He knew that the building would collapse rather than that. If he hadn't killed Yang Guang to eliminate the anger of various anti-armies, and then fostered a new emperor to barely stabilize the situation, it would be better to say that there are many elements that he envied Yang Guang for many years, and he hopes to be an emperor for a few days. This should be a morbid psychology accumulated by Yu Wenhuaji for many years. Excessive extravagance and waste will make people get lost in it and lose a lot of due judgment.
Assuming that Yu Wenhuaji didn't get lost in it, get carried away, he could fully support the new monarch, unite with the old forces of the Sui Dynasty and withdraw. On the one hand, it is the stability of the people in the world, on the other hand, it relies on the prestige of the imperial dynasty to find a way to fight back against the rebels from all directions. Perhaps the Great Sui Dynasty will not fall so soon, and Yu Wenhuaji and his son will not be pursued by the rebels from all walks of life. Of course, history is history, and there are not so many assumptions. We just look back on history and use their lessons to warn future generations.
