Di Renjie was an important courtier of Wu Zhou during Wu Zetian's reign, and his official title was Tongfengge Luantai Pingzhangshi. Di Renjie's population was unparalleled in the world, and because he ruled the country like a god, he saved the fate of the imperial court and became Wu Zetian's most trusted courtier. However, in order to restore Li Tang's world, Di Renjie's meticulous advance layout in the employment of personnel in the imperial court was to a certain extent deceiving Wu Zetian's wishes. Di was originally an old minister of the Tang Dynasty, just as the so-called people were in Wuzhou, and their hearts were tied to Li Tang, and it was precisely because of Di Ren's arrangement that the Shenlong government became smooth, so that finally Wu Zetian abdicated and Emperor Zhongzong of Tang succeeded to the throne.
During the Wu Zhou Dynasty, most of the high-ranking people in the imperial court were disciples of Di Renjie, such as Zhang Kamzhi, Huan Yanfan, Jinghui, Dou Huaizhen, and Yao Chong. It wasn't until after the Shenlong coup that Wu Zetian realized that Di Renjie was not recommending talents to Wu Zhou, but to Li Tang's restoration. Before his death, Di Renjie told Wu Zetian to return the government to Li Tang, and that his son was more important than his nephew so that Wu Zetian could make him die well.
As The most respected talent of Di Renjie, Zhang Kamzhi later became the same official as Di Renjie to tongfengge Luantai Pingzhangshi, in order to complete Di Renjie's lifelong aspirations and restore Li Tang's world.
As Wu Zetian's most trusted and respected prime minister, Di Renjie, in the end, found that his heart was still in Li Tang, and he was disappointed and also very angry. As a powerful monarch and emperor, she was finally betrayed by the person she trusted the most, which was indeed a heavy blow to her.
On December 16, 705, empress Dowager Wu Zetian died of illness at the Xianju Hall of Shangyang Palace at the age of eighty-two.
As Di Gong said, a generation of empresses Wu Zetian has done mixed things in her life, right or wrong, just as the wordless monument is still left for the world to evaluate.
