張楊
Dong Zhao wanted to flee to where Emperor Xian was. On the way, he passed by Henei Commandery, which was governed by the warlord Zhang Yang. Zhang Yang let Dong Zhao join him and appointed him as an official. In 192, when Cao Cao wanted to seek permission to pass through Zhang Yang's territory to receive Emperor Xian from exile, Zhang Yang initially refused, but after Dong Zhao's persuasion he agreed. Dong Zhao followed Cao Cao to receive the emperor.
