Traveling to the Three Kingdoms, I opened a blacksmith shop in Xuchang. Cao Cao came here every now and then to have a meal, and Dian Wei came here every day to drink. On the day Yuan Shu became emperor, I was frying spicy chicken in front of the stove. Cao Cao asked me what to do, and I said to attack his granary first. After hearing this, he slapped his thigh and sent out troops the next day. Half a month later, Shouchun City was destroyed, and Yuan Shu's dragon robe was still warm.
