In 618, the Sui Emperor Yang Guang was killed in Jiangdu, announcing the official demise of the Sui Dynasty. Yu Wenhua and thus became the heir to the Sui Dynasty's estate, and the army, harem, and courtiers were all controlled by him.
With the barrel of a gun, Yu Wenhua also wanted to seize power, so he led a 100,000 Xiaoguo army north, intending to occupy Luoyang as a base area. However, Li Mi, who had been attacking Luoyang for a year, allowed others to cut off Hu and defeat Yu Wenhua and kill him.
The attempt to Luoyang was fruitless, Yu Wenhua continued to go north, ran into a wall all the way, and was finally picked up by Dou Jiande. Nominally, Dou Jiande was still loyal to the Sui Dynasty, and was quite polite to Yang Guang's wife, children, and civil and military officials.
When these remnants of the fallen country met Dou Jiande, the embarrassing situation under the fence made them all silent, except for Yang Guang's eldest daughter Princess Nanyang, who looked at herself with ease, and when she talked to Dou Jiande about the hatred of the family and the country, she was very loud, and everyone who heard it was moved.
Princess Nanyang's husband, Yu Wenshiji, was Yu Wenhuahe's younger brother, and although he did not participate in his brother's usurpation, he expected that Dou Jiande would not forgive him, so he abandoned his wife and son and defected to Li Yuan halfway.
Princess Nanyang and Yuwen Shihe had a son named Zen Master, who should sit together according to Yu Wenhua and his crimes. Dou Jiande sent General Hu Benlang to Yu Shicheng to say to Princess Nanyang: "Hua and the Great Rebellion, the sons of brothers should sit together, if you are reluctant to be a Zen master, you can be extra-legal." ”
Princess Nanyang cut through the railway: "Since Tiger Benlang is a minister of the Sui Dynasty, why should I be asked about such a thing!" In this way, Zen Master Yuwen was ordained by Dou Jiande, while Princess Nanyang was ordained as a nun.
Later, Dou Jiande was killed in defeat, and Princess Nanyang returned to Chang'an, passing through Luoyang and met Yuwen Shi and him. Yuwen Shi and Gu Nian's old love for the husband and wife asked to meet with him, but princess Nanyang disappeared.
Yu Wenshi and he stood outside the gate of Princess Nanyang and asked for remarriage. Princess Nanyang said, "I am an enemy of you, and the reason why I didn't kill you was because you didn't participate when your brother was plotting rebellion." "Let him get out of here."
Yu Wenshi still did not leave, standing outside the door and pleading bitterly, Princess Nanyang was angry: "If you want to die, then come and see me!" Yu Wenshi and Princess Nanyang had already made up their minds, so they had to sigh and resign.
