Fu Jian, who claimed to be the King of the Qin Dynasty in the former Qin Dynasty, had a nephew named Fu Lang, whose courtesy name was Yuanda. Fu Jian called him Qianliju. After Fu Lang was transferred to the Jin Dynasty, he was appointed as the official minister of Wai Sanqi. He is considered to be the best among those who know the taste. He can even tell which part of the animal's body the meat he eats is located.

Sima Daozi, the royal family of the Eastern Jin Dynasty and King of Kuaiji, once hosted a banquet for Fu Lang, which included almost all the delicacies from the south of the Yangtze River. After the banquet, Sima Daozi asked: "What delicious food in Guanzhong can be compared with Jiangnan?" Fu Lang replied: "The dishes at this banquet taste good, but the salt is a little bit strong." Later, when I asked the waiter, it turned out to be true.

Later, someone killed a chicken and cooked it for Fu Lang to eat. Fu Lang took a look and said that the chicken was free-range and not cage-raised. After questioning, it was true.

It is said that Fu Lang once ate a goose and pointed out which piece of meat had white hair and which piece of meat had black hair. People did not believe it. Someone specially killed a goose and carefully recorded the similarities and differences in the coat color. Fu Lang's later description was accurate. People praised him as a rare gourmet who could not reach such a state without long-term experience.
