This person is the one who killed Emperor Sui Yang and seized Queen Xiao’s Yu Wenji. In reality, Laiyu Wenhua could only be considered a loser. He spent the first half of his life clinging to Yang Guang's lap, and the second half of his life was chased and beaten by all kinds of people. However, he is also a very interesting person. He once said, "If you die in life, why not become an emperor for one day?" After all, he is going to die, so it is better to be an emperor and enjoy it.

Yu Wenhuaji was the grandson of Yu Wensheng of the Shangzhu Kingdom of the Northern Zhou Dynasty. It is said that when he was young, he was spoiled and domineering. He only liked the strongest horses and the most precious treasures. I don’t know if this is the case, so he has a very discerning eye. Very good, he hugged Yang Guang's lap, and also made suggestions to help Yang Guang ascend to the throne. After more than ten years of good times, gradually all the heroes in the world came together, and the Sui Dynasty was almost exhausted. Yu Wenhuaji colluded with Sima Dekan and his younger brother Yuwen Zhiji to kill Emperor Yang of the Sui Dynasty.

At this time, Yu Wenhuaji had the most elite troops in the Sui Dynasty and could have stayed alive for two more days. Unfortunately, he also encountered the strongest rebel army, the Wagang Army, and both sides suffered losses in the end. Yu Wenhua and his elite were all scattered and could only flee in all directions. Fleeing to Wei County, he knew that his time was short, so he might as well become an emperor and die if he had too much fun, so he killed the puppet emperor and established the Xu Kingdom. Sure enough, less than a year later, he first attacked Weizhou for a long time, and then on the way to Liaocheng, he was flanked by Li Shentong and Dou Jiande, and was quickly captured.

Yu Wenhuaji has suffered repeated defeats. He overestimates his own capabilities and dares to proclaim himself emperor even if he occupies a small area. But he was such a loser, but he stirred up a lot of shit in the melee between the princes at the end of the Sui Dynasty. First, he killed Yang Guang, which directly led to the demise of the Sui Dynasty; second, he seriously injured Li Mi's Wagang Army, causing Li Mi had no choice but to defect to Li Tang, which also enabled Li Tang to have a place in the melee at that time.
