《梦溪笔谈·讥谑》
有个读书人要把酸梅和烧鹅送给别人，于是就在信里写道： 送上醋泡曹公一坛，汤煮右军两只，权且供饭食之用。 
有一士人遗人醋梅与燖鹅，作书云： 醋浸曹公一甏，汤燖右军两只，聊备于馔。 
A scholar was going to send sour plums and roast goose to someone else. Therefore, he wrote in a letter: I offer a jar of vinegar-soaked "Cao" and two servings of braised "youjun" so that you may eat them as a meal.
