Lady Sun saw herself as the sister of a powerful warlord, and not only acted in an arrogant, unbridled manner, but also allowed her bodyguards and personal staff to behave lawlessly in Jing Province. For this reason, Liu Bei specially appointed his general Zhao Yun, whom he deemed a serious and conscientious person, to oversee domestic affairs in Jing Province and maintain law and order. Around 211, Liu Bei left Jing Province on a campaign to attack the warlord Liu Zhang in Yi Province while Lady Sun remained behind in Jing Province. When Sun Quan heard that Liu Bei had travelled to Yi Province, he sent a ship to fetch her. Lady Sun attempted to bring Liu Bei's son Liu Shan, who was born to Liu Bei's other wife Lady Gan, with her to Sun Quan's territory. However, Zhao Yun and Zhang Fei, another of Liu Bei's generals, led their men to intercept her along the way and retrieve Liu Shan. Nothing was recorded in history about what happened to Lady Sun after she returned home.
