Erzhu Zhao was Erzhu Rong's nephew, and when he was young, he was known for his valor, physical strength and expertise in riding and archery, he was said to excel in armed combat so much that he could fight fierce beasts with his bare hands. One of Erzhu Rong's favorite activities as the chief of the Xiongnu Qihu (契胡) tribe was hunting, and of all his attendants, only Erzhu Zhao was able to keep up with him on hunts. Erzhu Rong therefore favored him greatly. However, once, when Erzhu Rong was asking his commanders for opinions on who could succeed him as the commanding general of the army if he were no longer there, most commanders opined that Erzhu Zhao could, but Erzhu Rong himself opined that Gao Huan was the only one capable of doing so, and he warned Erzhu Zhao, "You are no match for Gao Huan, and one day he will surely pierce through your nose." He also commented that Erzhu Zhao would be undefeatable as long as he commanded a cavalry force under 3,000 men—and that if he commanded more, his army would be in a state of confusion.
