Yu JIn

Yu Jin is a general who served Cao Cao since he first raised an army. In the Record of the Three Kingdoms, he is an established general and is known as one of the Five Generals of Wei. He won success in numerous battles and was known as a majestic and resilient man, but he frightened allies due to his strict disciplinarian behavior. On one occasion, Yu Jin was ordered to take control of Zhu Ling's troops, and met no resistance, as Zhu's troops were too terrified to resist the order. During the siege of Fan Castle, however, he surrendered to Guan Yu, and was a frail, old man by the time he returned to Wei, long after Cao Cao's death.
