《太平广记·卷二百五十八·嗤鄙一》
到第二年又参加考试，题目是关于水磨的论述，沈子荣又未动笔，人们又问到他时，他说：我能答的水磨是蓝田县的，今天问的是富平的水磨，我如何下笔？
至来年选，判水磑。又不下笔。人问之，曰：我诵水磑，乃是蓝田，今问之富平，如何下笔。
He took the exam again the next year, and the topic was about water mills. Shen Zirong didn't start writing again. When people asked him, he said: The water mill I can answer is in Lantian County. What is being asked today is about a water mill in Fuping. How can I answer it?
