I'm good at recipes, but I can't cook. Wang Yuyan in the culinary world means that he is knowledgeable about recipes, but he can't cook. Wang Yuyan is a character in Jin Yong's martial arts novel Tian Long Ba Bu. She is as beautiful as a fairy, and is the cousin of Gusu Mu Rongfu. In fact, her real identity is Duan Yu's cousin in Dali. The same is true of Wang Yuyan in the culinary world. Even if you know all the recipes, you just can't cook.
