In 705, Wu Zetian, who fell ill at Yingxian Palace, rarely left the palace. Except for Erzhang and Shangguan Wan'er, no one in the palace could easily enter it. After thinking of Zhang Kam's sight, he immediately led the army to move Wu Zetian to Shangyang Palace. He also helped Emperor Zhongzong of Tang to take the throne. In this ever-changing event, Shangguan Wan'er was not affected at all, but she was valued by Li Xian.
Although Li Xian was afraid of Wu Zetian and Empress Wei, he had long admired Shangguan Wan'er, and after succeeding to the throne, he was directly given the title of "Zhaorong". Since then, Shangguan Wan'er has left Wu Zetian and completed a magnificent turning point, becoming a real concubine of Erpin. His mother was given the title of Lady of the Commandments. Of course, Shangguan Wan'er was not bound by the cabinet, but continued to perform duties such as the canonical edict. Li Xian was a weak man, but the people around him, such as The Marquis of Wei, princess Taiping, and princess, were ambitious people.
Shangguan Wan'er had close ties with these people, and gradually formed a powerful force that bound Li Xian left and right. Wei Hou learned about Shangguan Wan'er's talent and regarded Shangguan Wan'er as his confidant. Wan Er pushed the boat along the water, repeatedly persuaded Wei Hou to follow Wu Zetian's example, and actively ran to recruit talents for him. Wu Zetian's nephew Wu Sansi, under the strong recommendation of Shangguan Wan'er, received the weight of Li Xian and Wei Hou. Under the heavy use of these people, Wu Sansi framed and expelled Zhang Zhizhi and other old ministers.
Wu Sansi is cunning. His development was due to the recommendation of Shangguan Wan'er, who had always had conflicts with Li Chongjun. At this moment, Shangguan Wan'er's dismal end was already doomed. In 707, Li Xianxian's daughter Princess Anle, with the support of all foreign relatives and ministers, repeatedly demanded that her father depose her brother Li Chongjun as crown prince and establish herself as the crown princess, inheriting her grandmother's old style. This made Li Chongjun unacceptable. Therefore, he led the Yulin army to rise suddenly, killed Wu Sansi, and went to Shangguan Wan'er's palace to kill him.
In Li Chongjun's actions, we can see that Shangguan Wan'er is no longer able to accommodate Li Chongjun's descendants. After Shangguan Wan'er escaped from this disaster, he still did not change. He continued to associate with Princess Taiping of Weihou and had contacts with many ministers. He also recommended the talented Cui Huang as prime minister. In 710, Li Xian died, and Shangguan Wan'er turned his head to Princess Taiping. In July of that year, Li Longji, the king of Linzi, took the lead in removing Wei Hou from emulating Wu Zetian in order to prevent him.
Shangguan Wan'er was also executed by Li Longji. Historians, after carefully studying the historical materials, believe that Shangguan Wan'er behaved correctly when he was at Wu Zetian's side, but Li Xian did not have the majesty of Wu Zetian and was quite conniving. During this period, Shangguan's mentality underwent a drastic change, and together with Empress Wei and Princess Taiping, he "manipulated power and was said by everyone". Such a person, when he came to Li Longji, could only cut the grass and remove the roots. The same is true of Princess Taiping.
