Zhang Yizhi
In 697, Zhang Changzong was referred to Wu Zetian, then ruling with the title of emperor—the only woman in the history of China recognized for doing so—by Wu Zetian's daughter Princess Taiping, to be Wu Zetian's lover. Zhang Changzong further told Wu Zetian that Zhang Yizhi was even more skillful than he was, and so Wu Zetian took Zhang Yizhi as a lover as well. Both were repeatedly promoted—Zhang Yizhi as the deputy minister of military supplies (司衛少卿, "Siwei Shaoqing")—and both were said to often put makeup on their faces and dressing in a beautiful manner. Their mother or mothers were given titles as grand ladies and Wu Zetian further ordered the chancellor Li Jiongxiu to serve as the lover for one of them. Even the most powerful officials flattered them, and referred them by endearing nicknames—Zhang Yizhi as Wulang and Zhang Changzong as Liulang (implying that Zhang Yizhi was the fifth-born son and Zhang Changzong was the sixth-born son of Zhang Xizang).
