Han Wendi's granddaughter, once a princess of the Northern Zhou Dynasty, why did she die at the hands of her uncle Yang Guang?

First of all, this is related to Yang Guang's personality. He himself was an emperor addicted to immorality and extreme cruelty. For Yang Guang, there is no one he can't kill. Even his younger brother Yong Yang died under his command, so killing a niece was as simple as eating and drinking water for Emperor Yang Guang of Yang Di.

Secondly, this is related to the rumors at that time. You should know that Yuwen Eying's husband was the pillar country of CoCo Lee at that time, and you should know that the pillar country had great power. For example, when Emperor Wendi of Sui Dynasty made his fortune, he was a pillar country of the Northern Zhou Dynasty. Then in this case, a fortune teller told Yang Guang. He said that everyone surnamed Li in the world must be killed, or the throne will fall into their hands.

Emperor Yang Di Yang Guang also heard this rumor, so he found an excuse to put CoCo Lee to death. Yu is his wife, so he didn't escape the fate of being killed. From the perspective of our descendants, this rumor was very accurate and finally fell into Li's hands. In addition, she is a representative of the remnants of the Northern Zhou Dynasty, so she still has some influence. There are many supporters standing behind her. These people were a great threat to Emperor Yang Di Yang Guang, who was afraid that one day they would rebel and seize the emperor's throne. Yang guang was particularly suspicious, so he executed Yu by thunder.

When Emperor Wendi was in office, he was very kind to his granddaughter and daughter-in-law, while Yang Guang had no scruples. After all, when people mention Yang Guang, "forcing his father to kill his brother" and "doing whatever it takes" are its inherent labels. Yu followed her husband shortly after being wrongly sentenced. So in the eyes of ancient emperors, there is no so-called blood relationship, as long as you threaten my rule, no matter who you are. I will find all kinds of excuses to kill you. Only in this way can I control my country safely.
