During the Western Wei Dynasty, Yu Wentai established the Eight Commanders of Zhu Guo, who later became the Guanlong aristocratic military group. These families are very prominent and have lasted for hundreds of years. At that time, birth was very important, and these prominent gate valves married each other to ensure their power. One of the nobles was Yu Jia, who flourished from the Northern Zhou Dynasty to the Tang Dynasty.
At that time, Emperor Xuanzong wanted to marry Yujia, so he wrote a letter to Princess Yongfu asking him to marry Yujia. At that time, being a Xu family member was not a glorious thing as most people thought. At that time, the prominent gate was often reluctant to marry the princess, because the princess was unruly and willful and easy to get involved in political disputes.
At that time, Tang Gaozong wanted to marry Princess Taiping to Xue Shao, but the Xue family didn't want to. This Princess Yongfu has been unruly and willful since he was a child. Although Emperor Xuanzong of the Tang Dynasty repeatedly taught her to be sensible, she always went her own way. Once, when Tang Xuanzong had dinner with her, she liked grilled fish very much, but the food was served late that day and she was very angry. At that time, she was only 15 years old, probably in a rebellious period. She directly broke the chopsticks and threw away the spoon, which immediately annoyed Tang Xuanzong.
Tang Xuanzong said bluntly, "There is a noble family in Yu Jia. Marrying you now can only embarrass me. I want to choose another princess. " Later, Emperor Xuanzong of the Tang Dynasty chose Princess Guangde, Princess Yongfu's sister, among the royal family. Princess Guangde is different from her sister. She is very knowledgeable. There is a special record in the Book of the New Tang Dynasty praising Princess Guangde, saying that she has her own manners.
