In essence, because Wu Zetian's throne came from the Li family, not the two thousand he won, nor was it passed to her by her father. If Wu Zetian's throne was passed to her by her father, it would be fine if her children's surname Wu continued to pass it, but her own throne came from the Li family, and it would be unreasonable not to pass it back to the Li family. Wu Zetian actually didn't have a good relationship with his brothers, so he sent them to a very far and wide place. Adding to the Di Renjie's statement, she felt that her son still smelled good.
Of course, combined with the political situation at that time, it is definitely not that simple, because after her death, it is still unknown that her nephew could really save the throne. A person who can be a wife for her son from a nunnery must be full of wisdom, and her choice must be the best. After Wu Zetian became emperor, he also welcomed the three ancestors of Li Tang, Emperor Gaozu, Emperor Taizong and Emperor Gaozong to the Xiangde Temple to worship. Once the Wu family succeeded, the sacrifices of these three countries would be extinct.
A minister said directly: Do you want Emperor Gaozong to become a starving ghost? This aspect was also considered carefully by Wu Zetian. But as far as Wu Zetian's two nephews are capable of giving them the true throne, who can they rely on? The border military officer group, the political group in the court, and the people's desire are all the Li family. Wu Zetian can suppress the imperial officials because of the identity of the empress dowager. Even Di Renjie, who was promoted by Wu Zetian, also favored the Li family. Wu Zetian really dared to let Wu Sansi succeed to the throne, unless she killed the Li Tang royal family first, including Li Xian Li Dan.
The main reason is that there is no one in the Wu family who can succeed. They are basically mediocre people and cannot control the situation at all. If there were such a person, they would definitely pass the throne to the Wu family. Perhaps the people in the Li family would have been extinct at that time. We have seen the ending passed to her son. There are also benefits to my mother's family. In order to prove the legitimacy of the throne, the Wu family will definitely try their best to defend Wu Zetian, describing her as a wise ruler who created a prosperous era, and even as the founding king.
