Yang guang promised her sister to be kind to her niece. Why did she poison her?

In 56 1 year (the first year of Baoding in the Northern Zhou Dynasty), Dugu Jialuo gave birth to the eldest daughter of Emperor Wendi of Sui Dynasty, named Lihua. In 568 AD, Emperor Wendi of the Sui Dynasty succeeded his father Qi Huangong, and Emperor Yuwen Yong of the Northern Zhou Dynasty took power, and hired his eldest daughter Yang Lihua as the princess of Prince Yuwen Yun.

Yang Lihua did not give birth to a son for the rest of her life, but gave birth to a daughter named Yu Wenye Ying. After her parents and husband died one after another, her daughter became the most important person in Yang Lihua. Therefore, before he died, Yang Lihua asked his younger brothers Yang Guang and Yang Di to be kind to his daughter and son-in-law, and Yang Guang agreed.

However, in the end, Yang Guang failed to fulfill his promise. He not only executed Yu's husband, but also poisoned his niece. Since he promised his sister to be kind to his niece, why did he poison her?

We should also start with Emperor Wendi of Sui Dynasty. Yang Lihua married Yu Wenyun as the crown princess, and after Yu Wenyun ascended the throne, she became the queen of the Northern Zhou Dynasty. But at this time, his father, Emperor Wendi of Sui Dynasty, had the idea of taking the position. Yu Wenyun is violent and indulged in pleasure. Less than a year in office, he passed it on to his son Yu Wenchan, but Yu Wenchan was only 6 years old.

Soon, Yu Wenyun died of illness, and Emperor Wendi took the opportunity to control the power of state affairs. Finally, Yuwen Chan was forced to abdicate, so Emperor Wendi of Sui Dynasty established the Sui Dynasty for Emperor Wendi of Sui Dynasty. As a result, Yang Lihua was directly reduced from the Queen of the Northern Zhou Dynasty to the Princess of the Sui Dynasty, which also led to a very embarrassing father-daughter relationship.

Yang Lihua was dissatisfied with his father's usurpation of power and was accused of national subjugation, but he was unable to stop it. He could only watch his father seize power. Although Emperor Wendi of Sui Dynasty took away the Northern Zhou Dynasty, he was also very distressed by his daughter, so he tried his best to make up for it, hoping to alleviate her pain.

Therefore, Yang Jian named Yang Lihua Princess Leping and allowed her to choose her husband herself. The granddaughter of the emperor wants to choose a husband, which is a great event. At that time, aristocratic children all ran out to choose. But choose to choose, Yang Lihua. Until CoCo Lee, the son of Li Chong, the secretariat of Youzhou, came to choose, Yang Lihua took a fancy to it and appointed it as his son-in-law.

This CoCo Lee is not only good-looking, but also top-notch in writing and martial arts. Yang Lihua for this son-in-law, no less attention, also for a pillar for him. Originally, for emperor Wu of song, the kingdom would not be given to Li, but he said:

The princess has made great contributions to me. Why should I cherish the official position from her son-in-law? Today, I awarded Zhu Guo.
