Gao Cheng
In 547, Gao Huan died, and Gao Cheng took over as regent. Princess Lou thereafter carried the title of Princess Dowager of Bohai. In 549, Gao Cheng was in turn assassinated by his slave Lan Jing (蘭京), and Princess Dowager Lou's second son Gao Yang assumed the regency. In 550, despite Princess Lou's reservations, Gao Yang had Emperor Xiaojing yield the throne to him, ending Eastern Wei and starting Northern Qi (as its Emperor Wenxuan). He honored her as empress dowager.
