东魏
In 547, Gao Huan died, and Gao Cheng became effective regent of Eastern Wei, dominating the political scene, and he soon considered taking the throne from Emperor Xiaojing of Eastern Wei. However, while preparing, he was assassinated by his slave Lan Jing (蘭京) in 549. In the aftermaths of Gao Cheng's death, Gao Yang, as the next oldest son of Gao Huan, took control of the Eastern Wei government. In 550, then bearing the title of Prince of Qi, had Emperor Xiaojing yield the throne to him, ending Eastern Wei and establishing Northern Qi as its Emperor Wenxuan. Despite the opposition of some officials (based on her Han ethnicity), Emperor Wenxuan created his wife Princess Li empress and created Gao Yin crown prince.
