This is a story from Three Kingdoms.
Huang Zhong, a veteran in the army of Shu, was one of its top five generals. Zhang He under Cao Cao had suffered one defeat after another. Cao Hong gave him a 5,000-strong army to attack Jiameng Pass. When Liu Bei learned this, he consulted with Zhuge Liang, his military advisor1. Zhuge Liang said: "Zhang He is a distinguished2（著名的） general of Cao Cao. Only Zhang Fei could defeat him." This irritated veteran Huang Zhong. Huang shouted: "Advisor has looked down upon me. I will get his head off and offer it to you." Zhuge Liang prodded3（刺，戳） Huang again by saying, "Though you are valiant4（英勇的） , I am afraid you are not Zhang He's match because you are too old." When Huang Zhong heard this, his gray hair angrily stood on end. He said, "Old as I am, I am able to open two bows and am full of vitality5."
Huang went down and got a big sword off the rack（现成的） and performed with it. He took two hard bows off the wall and pulled them broken. Then Zhuge Liang said: "If you go, whom would you like to be your assistant?" Huang Zhong replied, "Veteran Yan Yan. If the two of us can not defeat Zhang He, my gray-haired bead6 is yours." Liu Bei and Zhuge Liang were very pleased. The veteran generals were ordered to fight Zhang He. When Huang Zhong and Yan Yan got to Jiameng Pass, they laid a trap to defeat Zhang He. Then they used skillful tactics to take over Tiandang Mountain, the granary（粮仓） of Cao Cao's army. Later, they captured Dingjun Mountain. They reported back to Liu Bei and Zhuge Liang declaring a complete victory.
