Yao Chang
Yao Chang was born in 331, while his father Yao Yizhong (姚弋仲), a major Qiang chief, was a general under the Later Zhao emperor Shi Le. He was the 24th of Yao Yizhong's 42 sons. He was described as intelligent and deliberate, but uninterested in detail matters. After Later Zhao's collapse, Yao Yizhong submitted to Jin Dynasty (266–420) as a vassal, and, after he died in 351, his son Yao Xiang took over his troops and headed south to submit to Jin command. After realizing that the Jin general Yin Hao was greatly suspicious of him, however, Yao Xiang rebelled in 352 and ambushed Yin, and then occupied the cities in the Luoyang region (although not Luoyang itself), intending on establishing himself as the ruler of the region. During this time, Yao Chang served as one of his strategists. In a battle in 352, Yao Xiang's horse was killed, and Yao Chang yielded his horse to Yao Xiang—telling Yao Xiang that as long as he was still alive, the enemy would not dare to touch Yao Chang. However, as they were still discussing, they were rescued by their troops.
