Lady Sun
When Liu Qi died in 209 shortly after Liu Bei secured his position in southern Jing Province. All of Liu Qi's followers wanted for Liu Bei to succeed him as the new Inspector of Jing Province with his administrative seat at Gongan which he accepted. To further strengthen the Sun–Liu alliance, Liu Bei travelled to Sun Quan's territory to marry Sun Quan's younger sister, Lady Sun. After the political marriage, Sun Quan not only recognised the legitimacy of Liu Bei's control over southern Jing Province, but also agreed to "lend" Nan Commandery to him.
