Cao Cao's defeat in Chibi made him cry three times on the road: "Alas, filial piety, pain and pity." The purpose is threefold. 1. Sigh, sigh that Guo Jia died young. If he hadn't died, Battle of Red Cliffs might have won. 2. Ironically, the counselors under the account work harder. Step 3 pass the buck. Apparently, he ordered the ships to be connected by chains. Cheng Yu and Yu Xun reminded him to attack with fire. But he didn't listen. In order to save the king's face, one sentence made all the counselors blush.
