曹真
In any case, Cao Cao took pity on Cao Zhen, adopted him and allowed him to live with one of his own sons, Cao Pi. One day, while Cao Zhen was out hunting, he encountered a ferocious tiger which started chasing him. Cao Zhen turned back and killed the tiger with a single arrow shot. Cao Cao was so impressed with Cao Zhen's bravery that he appointed his adopted son as an officer in the elite "Tiger and Leopard Cavalry" (虎豹騎) of his army. Cao Zhen scored his first victory in battle when he defeated bandits in Lingqiu County (靈丘縣; east of present-day Lingqiu County, Shanxi). In recognition of his achievement, the Han imperial court enfeoffed him as the Marquis of Lingshou Village (靈壽亭侯).
