Li Shimin, the son of Emperor Taizong, was lying in the hospital bed, and the talented Wu Zetian waited on him. Li Zhi, the son of Emperor Taizong, came to visit his father. Wu Zetian also intends to seduce Li Zhi and plan for her future. In the long run, Li Zhi and Wu Zetian had an affair. Later, after the death of Emperor Taizong, according to the system of the Tang Dynasty at that time, concubines who had no children in the harem had to go to Ganye Temple for a haircut. Wu Zetian was a Wu Cairen in the period of Emperor Taizong 12 years. She had never given birth, so she had to go to a temple to become a nun. During this period, because Wu Zetian and Tang Gaozong Li Zhi had some ambiguous feelings, Li Zhi could not forget Wu Zetian for a while, so he often visited Wu Zetian in the harem. When they met, Wu Zetian expressed her love for Li Zhi, and also wrote many love poems for Li Zhi according to her talent to express her feelings of missing Li Zhi. The most famous poem "Ruyi Niang" is written like this. Zhu Jian thinks in succession, looking haggard and fragmented. Do not believe that I will shed tears and untie my pomegranate skirt? . This affectionate love poem was very helpful to Li Zhi, and later Li Zhi was even more fond of Wu Zetian.
At that time, Tang Gaozong Li Zhi had a favorite concubine, Xiao Shufei, and a queen in the palace. At that time, there were many concubines in Li Zhi harem, which was as beautiful as a cloud. If Wu Zetian wants to remind Li Zhi of herself among these women, she can only make Li Zhi fall in love with herself. In this way, she has a chance to leave the temple and return to the palace. Therefore, Wu Zetian desperately grasped Li Zhi's lifeline and wrote those tender poems to impress Li Zhi.
Through these sentimental poems, we can see that Wu Zetian should have liked Li Zhi at that time. Fortunately, Li Zhi lived up to Wu Zetian's true feelings, recalled Wu Zetian to the palace as a princess, and soon gave birth to his son Li Hong, who was named the second-class Zhao Yi. The cruel and decisive Wu Zetian originally had a gentle side.
