In 677 (the second year of Yifeng), Shangguan Waner was summoned by Wu Zetian in the palace and put forward a proposition on the spot, asking him to write according to the topic. Shangguan Waner's words were written in an instant, with smooth meaning, gorgeous words and beautiful language. Wu Zetian saw the great joy and immediately ordered him to be exempted from his handmaiden status and put him in charge of the imperial edict of the palace. Soon, Shangguan Waner committed a capital crime for disobeying the will, but Wu Zetian cherished her literary talent and pardoned her, only to be punished. In the future, Shangguan Waner served meticulously and catered to Qu Yi, which won the favor of Wu Zetian.
Starting from 696 (the first year of Tian Tong) (the year when the old Tang Dynasty was sacred), Wu Zetian asked her to handle the list of thoughts and participate in government affairs, and her power became more and more powerful. In 705 (the first year of Shenlong), after Tang Zhongzong was reset, Shangguan Waner was asked to draft the imperial edict specially, which won the trust. She was also honored as Mrs. Zheng, her mother. In 706 (the second year of Shenlong), relying on the support of Princess He Anle, he successively designed Xia Sha, Huan, Jing Hui and Cui to become creditors. Shangguan Waner had an affair with him again. In her imperial edicts, she often praised Wu Shi and suppressed the royal family, which made Prince Li Zhongjun very angry.
In 707 (July of the first year of Jinglong), Li Zhongjun and Li Duozuo, the general of Zuo Yulin, etc. The fake imperial edict dispatched more than 300 people from Yulin army to the mansion of Wu Sansi and Wu Chongxun, killed them and punished pro-Party 10 people. Then, they led their troops through Zhang Sumen and knocked on the door of the cabinet to look for Shangguan Waner. In desperation, Shangguan Waner fled to Tang Zhongzong and Wei Hou, and threatened: "Seeing the prince means killing Shangguan Waner first, and then arresting the queen and your majesty in turn." At that time, Zhongzong was furious, so he took Shangguan Waner and Princess Anle to Xuanwu Gate to avoid the soldiers' front, and made General Liu Fei, the right feather forest, gather in front of Taiji Hall and guard it behind closed doors. Prince Li Zhongjun was defeated and killed.
Since then, Shangguan Waner often persuaded Zhongzong to set up a large number of bachelors in Zhaowen Museum, recruiting talents at that time, hosting banquets for entertainment many times, and singing poems. Shangguan Waner replaced Zhongzong, Wei Hou and Princess Anle at the same time every time, and made several beautiful poems, which were mostly sung by people at that time. For the poems written by ministers, Zhongzong ordered Shangguan Waner to comment, and the first prize was often awarded to Jin Jue, which was priceless. As a result, both inside and outside the imperial court, poetry and fu became a common practice.
In Shangguan Waner's residence, the Chinese faction also wears ponds to build stones, and the carvings are extremely exquisite, often leading ministers to feast. At that time, the palace was forbidden and spacious, allowing palace officials to enter and leave at will. Shangguan Waner and some palace officials bought luxury houses outside the palace, and they often made contacts with them, and some people got high positions as a result. Cui, assistant minister of Zhongshu, was later taken for granted for having an affair with Shangguan Waner in the outhouse. Soon, Cui cheated for personal gain many times when presiding over the election. He was impeached by Li Shang and demoted as a foreign Sima. Because Shangguan Waner and Princess Anle interceded for him, he was reinstated.
In 7 10 (the fourth year of Jinglong), Princess Taiping became stronger and stronger, and Shangguan Waner was attached to Princess Taiping. In June, after Tang Zhongzong was poisoned by Wei Ruyun and Princess Anle, Shangguan Waner and Princess Taiping drafted a testamentary edict and made Li Zhongmao the Crown Prince. Wei Ruyun knew politics, and Li Dan, the king of Xiang, participated in the state affairs. In July, Li Longji, king of Linzi, led Yulin soldiers into the palace and killed Wei Hou and his henchmen. Shangguan Waner greeted the imperial secretary with a candle and showed Liu Youqiu the testamentary edict drawn up by her and Princess Taiping. Liu Youqiu interceded with her testamentary edict in Li Longji, but Li Longji refused to let her kill Shangguan Waner.
In 7 13 (the early years of kaiyuan), Emperor Xuanzong of the Tang Dynasty sent someone to collect the poems of Shangguan Waner, and compiled them into 20 volumes, making Zhang Shuoxu. In this collection of poems, The Whole Tang Poetry only contains 32 poems.
