Emperor Ming
In 577, after Northern Zhou's Emperor Wu conquered Northern Qi and seized its territory, Emperor Ming went to greet Emperor Wu at Northern Qi's former capital Yecheng. Initially, while Emperor Wu treated Emperor Ming with ceremonial respect, he did not consider Emperor Ming as an important vassal. Emperor Ming sensed this, and, at a feast, discussed how Emperor Ming's father Emperor Xuan owed much to Emperor Wu's father, Western Wei's paramount general Yuwen Tai, and in doing so was so emotional that he wept bitterly. Emperor Wu was impressed, and treated him with greater respect. Emperor Ming also spent much effort to flatter Emperor Wu—including comparing him to the mythical emperors Emperor Yao and Shun. Emperor Wu was flattered, and rewarded Emperor Ming with much treasure, as well as some of the Northern Qi emperor Gao Wei's concubines.
