Tang Zhongzong Li Xian is the son of Wu Zetian. He was emperor twice in his life. Li Xian has a high background, and he is the eldest son of the Queen. He ascended the throne twice, so he was called "Six Emperors Pill". His father Tang Gaozong Li Zhi succeeded him, his brother Tang Ruizong Li Dan, his son Tang Shaodi Li Chongmao, his nephew Tang Xuanzong Li Longji as emperor, and so did his mother Wu Zetian.
Like the homonym of Liuwei Dihuang Pill, Liuwei Dihuang Pill is a medicine for nourishing yin and tonifying kidney, and it is mainly used for "soreness of waist and knees". However, Tang Zhongzong Li Xian's character has always been weak, and he has been weak all his life. Li Xian was made a prince by his father Tang Gaozong Li Zhili at the age of 24. After Li Zhi's death, Li Xian ascended the throne and became emperor. His mother, Wu Zetian, was merciful and proclaimed herself emperor. Surprisingly, one month later, Li Xian was forcibly removed from the throne and sent to Zhou Fang, where he stayed for 15 years.
Wu Zetian finally made Li Xian the Crown Prince again. Soon, Zhang Jianzhi and others began to implement "changing dragons" to make Li Xian proclaimed himself emperor again, but Li Xian still had no real power. He still has to face the powerful Wu family, and he has to support his equally powerful and ambitious wife Webster. After suffering for more than 10 years, Li Xian had to compensate his wife and daughter, so he entertained himself and made up for everything he lost regardless of state affairs.
In order to compensate his wife Wei Ruyun and his daughter Princess Anle, he gave all the power to them. Li Xian is also weak and doesn't care about anything.
