Wei Tuan'er came from a humble origin, and was initially just a rough palace maid in Wu Zetian's palace. However, she was quite scheming, and tried her best to flatter in front of Wu Zetian, and finally she was able to serve closely by Wu Zetian's side, which was quite favored. Wei Tuan'er later used his strength to speak in front of Wu Zetian, and often flaunted his might. But she is quite ambitious and is not willing to be a palace maid for the rest of her life. So Wei Tuan'er chose a target, he was Li Dan, the son of Wu Zetian.
Li Dan was cowardly by nature, but after all, he was Wu Zetian's own son, and his future future was unknown. And most importantly, Wei Tuan'er valued Li Dan's feelings and took great care of his two concubines, Dou and Liu. Wei Tuan'er believed that if he married Li Dan, he would definitely be able to suppress Dou and Liu with his own wrists and become Li Dan's favorite.
So Wei Tuan'er tried his best to seduce Li Dan, but Li Dan was not hooked. Li Dan did not like women who were scheming, nor did he like Wei Tuan'er's shrewd and calculating appearance. But Wei Tuan'er was just unwilling to give up, always teasing Li Dan openly and secretly. Once, she provoked Li Dan, and Li Dan directly reprimanded Wei Tuan'er in front of everyone without mercy. Even if Wei Tuan'er won wu Zetian's favor again, she was just a palace girl, and Li Dan's reprimand still had to listen honestly.
However, this incident greatly stung Wei Tuan'er's self-esteem, and she vowed to take revenge on Li Dan. It was impossible to directly attack Li Dan, so Wei Tuan'er took a different path and thought of opening a knife on Li Dan's concubines Dou and Liu. Wei Tuan'er knew that Wu Zetian hated the art of victory the most, so she secretly informed Wu Zetian, saying that Dou and Liu secretly cursed Wu Zetian for his early death. Wei Tuan'er also took Wu Zetian's nephew Wu Chengsi, who had long seen that Li Dan was not pleasing to the eye, and wanted to pull Li Dan into the water by slandering Dou and Liu.
Wei Tuan'er's words were conclusive, and Wu Zetian had to believe them. But she also had other thoughts, after all, Li Dan was her own son, and he was usually low-key and smooth, and Wu Zetian thought that the Liu clan of the Dou clan should be carrying out the art of victory behind Li Dan's back. So on the second day of the first lunar month, she left Dou and Liu, who had entered the palace alone to invite An, and secretly executed them, even disposing of the corpses together. After the execution of the two, Wu Zetian also intended to test the thoughts of his son Li Dan, so he ordered someone to inform Li Dan of the death of Dou and Liu.
Although Li Dan is cowardly, he is not incompetent. He understood that his mother Wu Zetian wanted to test his loyalty, and he did not dare to be half unhappy on his face, but instead fell to his knees on the mountain and cried out long live to show his loyalty and innocence. Wu Zetian was very satisfied with Li Dan's performance. However, Wu Chengsi was unwilling to let Li Dan go like this. He quietly ordered Li Dan's subordinates to be tied up and tortured, forcing them to speak unfavorably to Li Dan.
After this matter was known to Wu Zetian, she was furious and severely punished Wu Chengsi, and then sent someone to appease her son Li Dan. After this incident, Wei Tuan'er completely froze with Li Dan, and she didn't care, she continued to search for her next target.
However, Wei Tuan'er's dream was still shattered, and later the East Window Incident occurred, and the things she falsely accused were exposed, and finally she lost her life to atone for her sins. After Li Dan became emperor, he secretly searched for the bones of the two concubines many times, but never found anything. In the end, Li Dan could only set up a crown tomb for the two women, which was a way to express his guilt.
