Zhao Yun (? -229), the word Zilong, was born in Zhengding, Changshan (now Zhengding, Hebei). Zhao Yun is eight feet long and commanding. He is one of the famous Shu and Han dynasties, and the warlords at the end of the Han Dynasty scuffled. Zhao Yun was selected by the county magistrate to lead Yi Cong to join the White Horse General Gongsun Zan. During this period, I met Liu Bei, a relative of the Han Dynasty royal family, but soon Zhao Yun left because of his brother's death. Zhao Yun left Gongsun Zan for about seven years, met Liu Bei in Yecheng, and followed Liu Bei from then on. Zhao Yun followed General Liu Bei for nearly 30 years, participated in Bowangpo Campaign, Changbanpo Campaign and Jiangnan Pacification Campaign, and commanded the Battle of Entering Sichuan, Hanshui Campaign and Ji Gu Campaign alone, all of which achieved very good results. In addition to fighting everywhere, Zhao Yun also took the partial general as the prefect of Guiyang, leaving Sima to stay in the camp and supervise Jiangzhou with the general of Yijun. In addition, when Zhao Yun pacified Yizhou, he quoted the story of Huo Qubing to persuade Liu Bei to return the land to the people. After Guan Yu and Zhang Fei were killed, he advised Liu Bei not to cut Wu. After Zhao Yun's death, Liu Chan ordered a memorial service for Zhao Yun. Jiang Wei regards Zhao Yun as a smooth and smooth Hou, "gentle and courteous, kind-hearted, smooth and smooth, the deacon has a lesson to be smooth, and is determined to be smooth in adversity."
