For thousands of years, Yu Wenhuahe has been regarded as the culprit who killed Yang Guang and usurped power, and people called him the tyrant of the late Sui Dynasty. In fact, Yu Wenhua and he are not tyrants at all, and he is only the mastermind of killing Yang Guang, and the black hand behind the scenes is his younger brother Yuwen Zhihe.
Yu Wenhua is an out-and-out clumsy disciple, which is probably related to the Yuwen family's family style. Yu Wenhua and his father Yuwen Shu were great generals of the Sui Dynasty, with high authority, and under this big tree, the people of the Yuwen family were more arrogant than one.

Soon after the establishment of the Sui Dynasty, the original nobles and heroes were deeply rooted, and the children of the nobles of the upper class indulged in the life of dogs and horses all day long, and Yu Wenhua was one of them. His father's spoiling made Yu Wenhua and Yuwen Zhi and the two brothers develop a greedy and arrogant personality, they did wrong, ignored the law, and dared to oppress the people at the feet of Tianzi.
It was such a clumsy brother-in-law, but he became the court guard officer of Prince Yang Guang. The guards in the East Palace are responsible for the safety of the prince, and Yu Wenhua is close to Yang Guang, and in the eyes of outsiders, he looks like a princeling. Climbing the towering tree of the prince, Yu culture and his position in the DPRK rose, and countless people gave him gifts.
Yu Wenhua and Fu Shao were dismissed from office for accepting bribes, but due to Yang Guang's favor, Yu Wenhua and often quickly reinstated officials. From this point, it can also be seen that Yang Guang is indeed too emotional and unprincipled in doing things, and his connivance with Yu culture is actually a portrayal of the entire smoky miasma of the imperial court.
Soon after, Yu Wenhua and his younger brother married Princess Nanyang, and the relationship with the emperor was further strengthened. With this layer of relationship, Yu Wenhua became more and more arrogant, even if he was a hundred officials and secretaries of state, he often did things rudely, and it was common for him to say wild words. After the Sui Dynasty Emperor ascended the throne, Yu Wenhua was promoted to the rank of Taibu Shaoqing, and with his status as emperor, Yu Wenhua and even more wanton behavior, so that he dared to openly disobey the edict and trade with his younger brother Yuwen Zhi and the Turks. The Turks were a fierce enemy of the north during the Sui Dynasty, and the threat to the Sui Dynasty has always been great, and Emperor Wen of Sui and Emperor Ju of Sui have ordered that they should not trade with the Turks to prevent military horses, iron and so on from flowing into the north. Yu Wenhua and this time stabbed the honeycomb, without punishing him, Yang Guang, the emperor, could not do it.
Yang Guang imprisoned Yuwen Wenhua and Yuwen Zhi and prepared to execute them to make an example. However, at the last moment, Yang Guang made another mistake, and as soon as Princess Nanyang came to intercede, Yang Guang softened his heart, but only ordered Yuwen Shu to put Yu Wenhua and house arrest and strictly discipline him. Yuwen Shu pleaded with the emperor before his death, and Yang Guang not only ordered that Yu Wenhua and Yuwen Zhihe be spared, but also made Yu Wenhua and an official. At this time, Yang Guang could not have imagined that he would die at the hands of the Yuwen family in the future.
Yang Guang really couldn't imagine it, because Yu Wenhua was indeed a waste, a complete clumsy disciple, for Yu Wenhua and for him, the courage to rebel against the king was not there, at best, he was just using the emperor's favor to arrogantly and arrogantly in the court, doing evil things to bully men and women.
The people who really killed Yang Guang were Yang Guang's Xiaoguo Army and Yuwen Zhiji. Yang Guang named his own guard XiaoGuo, and the leader of this guard was Sima Dejie. In the last year of Daye, the world was already in chaos, and the flames of the uprising were ignited in the north, but Yang Guang seemed to abandon himself and ran to the south with the Xiaoguo army to enjoy it.
Yang Guang's posture of planning to abandon the north was unacceptable to the Xiaoguo soldiers, most of them were from the Guanlong region, and their wives, children, old and small families were all there, so it was naturally impossible for them to give up these and stay in the south with Yang Guang.
Of course, as Yang Guang's guard, the Xiaoguo Army still had loyalty to Yang Guang, and ordinary soldiers would not have the courage to kill the king, they just wanted to go back quickly. Xiao Guo's commander Sima Dejian was different, and this person whom Yang Guang trusted very much saw that the army was unstable, and he had the idea of rebellion in his heart.
However, the most ruthless is Yuwen Zhihe, and the biggest difference between this stupid boy and his brother is that he has greater ambitions. After Yuwen Zhi and Sima Dejie heard that Sima Dejie was planning to rebel, he found Sima Dejie and persuaded him to kill Yang Guang directly and seek to win the world. Yuwen Zhi and Sima Dejie hit it off immediately, but such a big thing must have a leader.
Yuwen Zhihe entrusted this "heavy responsibility" to his brother, but When Yu Wenhua was a person who did not have any courage, as soon as he heard that he was going to be the leader of the rebel army, he was immediately frightened and scattered, and he broke into a cold sweat.
The Book of Companions reads: "The nature of the nature of the transformation and nature is timid, the first smell is great fear, the color is sweating, and the long time is determined." ”
Yuwen Zhihe comforted yu wenhua for half a day, and after giving Yu Wenhua and the big cake of the success of the rebellion, Yu Wenhua and this little stabilized their minds and agreed to be the leader of the rebels.
Although it was Yu Wenhua who ordered Yang Guang's killing, it was not he who really launched a mutiny to hunt down Yang Guang and start a crime, and the real culprit behind it was his younger brother Yuwen Zhihe.
"The things that jiang all kill and rebel, and the wisdom and the plot are also." (Book of Sui)
In fact, even after killing Yang Guang, Yu Wenhua still did not have the consciousness that a rebel leader should have. The rebellion was successful, Yu Wenhua and the first thing that came to mind was enjoyment, he took all of Yang Guang's harem beauties, and went to his own voice, and the rest of the things were all handed over to Yuwen Zhi and others. In order to dress up beautiful women and treasures, Ubun and robbed thousands of cattle, and let the soldiers carry armor and weapons.
Yu Wenhua and a series of operations caused anger and resentment, the people complained about him, and the soldiers were indignant, thinking that it was really eight lifetimes of mold to meet such a leader.
In fact, Yu Wenhua and his actions can also be understood, this stupid boy who only has pleasure in his brain has no ability to rebel at all, without Yuwen Zhihe, and if he lends him a boldness, he does not dare to kill Yang Guang.
Therefore, after the defeat of Li Mi's Wagang Army, Yu Wenhua has been complaining about Yuwen Zhihe, believing that he should not have killed Yang Guang. Before dying, Yu Wenhua said a sentence, "Life should be dead, isn't it a day to be an emperor?" Then he killed the puppet emperor and called himself emperor enjoyed it. Soon after, Yuwen and Dou Jiande captured him, and he and his younger brother Yuwen Zhihe were beheaded.
