Although Cixi has all the power in the world, she never wanted to be an emperor like Wu Zetian, did she?

Yes, she never considered being an emperor herself. Because the situation in the Qing Dynasty was completely different from that in the Tang Dynasty: the royal family itself was a descendant of Hu, and although it strongly admired the Han civilization, it was still the most open and compatible in all previous dynasties, and reluctantly accepted women as emperors; After the Song Dynasty, Neo-Confucianism flourished, and women were subject to more restrictions, especially in the Ming and Qing Dynasties. Cixi wanted to be an emperor, but the Manchu dignitaries would not support it, and the gentry in the world would not accept it.
