公孙瓒
Around the early 190s, Zhao Yun met Liu Bei, who was taking shelter under Gongsun Zan at the time. Zhao Yun became very close to Liu Bei and desired to switch his allegiance to Liu Bei. When Gongsun Zan sent Liu Bei to assist his ally, Tian Kai, in a battle against Yuan Shao, Zhao Yun followed Liu Bei and served as a cavalry officer under Liu Bei.
