Although Wu Zetian was the 1 female emperor in the history of China, she could not have made great achievements without the help of Tang Gaozong. And Tang Gaozong will meet Wu Zetian at Kanye Temple because he likes Wu Zetian very much. In order to improve the status of Wu Zetian, he even snubbed his original wife, Queen Wang. Before Wu Zetian entered the palace, Xiao Shufei was a favorite of Tang Gaozong, but after Wu Zetian entered the palace, Xiao Shufei fell out of favor. Originally, she and the queen were bitter rivals in love, but their position in the palace was threatened by Wu Zetian, so they reached an alliance.
However, the alliance without the emperor's favor is particularly fragile. They were brutally killed after Wu Zetian became queen. Since then, Wu Zetian has no threat in the palace. Speaking of the reason why Tang Gaozong let Wu Zetian participate in politics, it has a lot to do with his own ability. Tang Gaozong was originally a weak and indecisive person. He always hesitates when dealing with state affairs. Without the help of Wu Zetian, Tang Gaozong would be caught off guard in front of state affairs.
For example, once the Tang Dynasty was attacked by Koguryo, Tang Gaozong didn't know which general to send, and he didn't know whether to pursue the pro-China policy or the counter-offensive policy. At this time, Wu Zetian gave Tang Gaozong timely guidance, telling him that he should mobilize military forces to fight Koguryo. It is precisely because of Wu Zetian's outstanding political talent that Tang Gaozong paid attention to her. From then on, Tang Gaozong trusted Wu Zetian more. When he was in poor health in his later years, he simply entrusted all political affairs to Wu Zetian.
