In the battle of Chang Ban Po, Zhao Yun is responsible for protecting Gan, Mi and A Dou, but due to the chaos of war, Zhao Yun gets separated from them, so he leads 30-40 followers to go back and look for them, but after looking around, he fails to find them but kills Chun Yu and saves Mi Zhu and Gan. Zhao Yun sent them to Chang Ban Bridge and was almost misunderstood by Zhang Fei as betraying Liu Bei, thanks to the explanation of Jane Yong to clarify the fact. Zhao Yun then entrusted Mrs. Gan to Zhang Fei and turned back to look for Ah Dou, but at that time he was alone, without an attendant.
