Hanzhong Campaign
Zhang Liao rendezvoused with Cao Cao, who had returned after being defeated in the Hanzhong Campaign, at Mobei (摩陂; in present-day Jia County, Henan). Cao Cao rode in a carriage and went out to personally receive Zhang Liao. He then relocated Zhang Liao to the garrison at Chen Commandery (陳郡; around present-day Zhoukou, Henan).
