Yang Yuhuan's natural beauty and superior educational environment make her have a certain cultural accomplishment, graceful personality, proficient in temperament, good at singing and dancing, and good at playing the pipa.
In July of the 22nd year of Kaiyuan, Princess Xianyi, the daughter of Emperor Xuanzong of the Tang Dynasty, held a wedding in Luoyang, and Yang Yuhuan was also invited to attend. Li Mao, the younger brother of Princess Xianyi, fell in love with Yang Yuhuan at first sight. At the request of Wu Huifei, Emperor Xuanzong of the Tang Dynasty wrote a letter asking her to be the shroud princess of that year. After marriage, the two are extremely sweet.
Wu Huifei died in the 25th year of Kaiyuan (737). Li Mao's mother, Wu Huifei, was the favorite concubine of Emperor Xuanzong of the Tang Dynasty, and she was treated as a queen in the palace. Xuanzong was unhappy for this. At that time, the harem Qian Qian was absolutely meaningless. Some people suggested that "the courtyards should be full of manners", and Xuanzong called Yang into the harem.
