Moreover, when Wu Zetian was in power at that time, she was questioned by many people, saying that women could not interfere in state affairs and had a great influence on Wu Zetian. Therefore, Wu Zetian, who learned from the past, could not let her daughter Princess Taiping succeed to the throne. After all, the emperor's position is not suitable for Princess Taiping, so Princess Taiping can't inherit the throne anyway.
In addition, at that time, civil and military officials in the Qing Dynasty strongly opposed Princess Taiping's succession to the throne, so Wu Zetian had no way to let her grandson Li Longji inherit the throne. Although Princess Tian Ping is stronger than this Li Longji, she can't escape the bondage of the idea that women can't be in power, which leads to Princess Tian Ping giving up the right to inherit the throne and giving this position to Li Longji, which makes Li Longji naturally become the emperor.
So in ancient times, even if you were a talented daughter, you would be bound by many things, so Princess Tian Ping could only lose to Li Longji.
