Wu Zetian was the only female emperor in Chinese history to formally ascend the throne and listen to the government of the tang dynasty, and her appearance changed almost the entire political pattern of the Tang Dynasty. After Wu Zetian, many women wanted to emulate her to the top of power, but unfortunately none of them succeeded. Wu Zetian's place in Chinese history is unique.
Wu Zetian's favorite was his daughter Princess Taiping, only because Princess Taiping was very similar to her in temperament and appearance. With such a mother in front, Princess Taiping was also very ambitious about politics. She married twice in her life and had seven children with her two husbands, including 4 sons and 3 daughters. Princess Taiping was not a qualified mother, as she spent most of her life fighting politically.

Xue Chongjian was the son of Princess Taiping and her first husband, Xue Shao, who was later executed by Wu Zetian for his involvement in the rebellion. After Xue Shao's death, Princess Taiping remarried to Wu Youji with the four children she and Xue Shao gave birth to. Xue Chongjian was equivalent to a drag oil bottle at this time, although he was the princess's own flesh and bones, but he could not get any benefits in front of Wu Youji. The better the relationship between Princess Taiping and Wu Youji, the more embarrassing Xue Chongjian's situation became.
As he grew older, Xue Chongjian became more and more disgusted with his maternal grandmother Wu Zetian, who had executed his own father. He hated his mother and grandmother very much, and his relationship with them deteriorated. It was at this time that Xue Chongjian and Li Longji came together and became close friends. Because the situation of the two people is similar, that is, the birth mother was executed by order of Wu Zetian. Li Longji and Xue Chongjian felt sorry for each other, and later Li Longji's father Li Dan competed for the throne, and Xue Chongjian made a great effort.
At that time, Princess Taiping's faction was still on Li Dan's side, but after Li Dan ascended the throne, Princess Taiping's relationship with him became worse and worse. However, Xue Chongjian still firmly supported Li Dan and Li Longji, which made Princess Taiping very angry. Princess Taiping often openly reprimanded Xue Chongjian for this, and even whipped him with a long whip in the street. These things Li Longji piled up piece by piece in mind. Later, Princess Taiping lost in the political struggle, the so-called king was defeated, and Li Longji did not leave a way for Princess Taiping to survive and did not allow her to turn around in the future.
Li Longji ordered that Princess Taiping be beheaded, and of the 7 children born to Princess Taiping, only Xue Chongjian was saved, and all the others were executed. Xue Chongjian not only did not have to worry about his life, but was given the surname "Li" by Li Longji, and also promoted him to a knighthood. Some people accused Xue Chongjian of being a cold-blooded and ruthless person, sitting back and watching his brothers, sisters and mother being executed.
But in fact, from Xue Chongjian's point of view, his choice to support Li Longji instead of his mother Princess Taiping was a perfectly normal decision. First of all, Princess Taiping did not value Xue Chongjian's son, and the relationship between the two had always been very tense. On the contrary, Xue Chongjian and Li Longji have a very good relationship, and the two are close friends. If the princess succeeds in seizing power, Xue Chongjian does not have the so-called opportunity to go further. And if Li Longji ascends to the throne, he will destroy his relatives from the great righteousness of the Dragon's Merits, not only to save his life, but also to make great progress in his career.
