There is a dialogue between Liu Bei, Guan Yu and Zhang Fei in the story of San Gu Mao Lu.

Guan Yu: "It's too polite for my brother to visit twice in person. In my opinion, Zhuge Liang is only in name only, and he has no real talent and learning, so he repeatedly evaded and dared not come to see you. "

Liu Bei: "That's not true. At first, Qi Huangong wanted to meet the savage of Dongguo, and he went there five times before he met him. What's more, what we want to see today is a great sage!"

Zhang Fei (contemptuously): "Great Sage? Think of him as a village man, and you can be called a great sage! If my brother doesn't come, I'll tie him up with a hemp rope! "

Liu Bei (angrily): "How can you be so rude! Haven't you heard about Zhou Wenwang's visit to Jiang Ziya? How can you be so rude when the king of Wen respects the virtuous so much! Don't go! I'll go with Yun Chang. "

Zhang Fei: "My two brothers are going. How can I not go?"

Liu Bei: "If you must go, you have to rely on me."

Zhang Fei: "Which one?"

Liu Bei: "Don't be rude."

Zhang Fei: "I just listen to my eldest brother."
