During his mission to Wu, Fei Yi kept his cool when the Wu emperor Sun Quan tried to ridicule and poke fun at him. Sun Quan treated Fei Yi to alcoholic drinks, saw that he appeared drunk, and then bombarded him with a series of questions about current affairs. Fei Yi gave an excuse that he was no longer sober and declined to answer immediately. He noted down all the questions, went back and thought through carefully, and came back to Sun Quan later with all the answers without missing out any question. Some Wu officials such as Zhuge Ke and Yang Dao (), who were known for their oratorical talents, attempted to challenge Fei Yi and pose difficult questions to him. However, Fei Yi managed to respond in a calm and dignified manner, and provide well-reasoned answers to their questions. He held his ground well throughout his mission.
