Who was Yue Jin?
Yue Jin, style name Wenqian, was a military general serving under the warlord Cao Cao in the late Eastern Han Dynasty. He was noted as much for his short stature as for his valour and ferocity on the battlefield. Yue Jin participated in most of Cao Cao's early military exploits, and gained multiple successes in the campaigns against Lü Bu, Liu Bei and remnants of the Yellow Turban rebels and the Yuan clan of northern China. He was particularly praised as a capable vanguard, but his most famed accomplishment came with his supporting role in the defence of Hefei against the advances of Sun Quan's forces at the Battle of Xiaoyao Ford in 214.
Chen Shou, the author of the Records of the Three Kingdoms, considered Yue Jin among the Five Elite Generals, along with Zhang Liao, Yu Jin, Zhang He and Xu Huang, and referred to him as the most ferocious of all Cao Cao's generals.
