《世说新语·文学》
于法开提醒他的弟子说： 道林开讲《小品》，等你到达时，就该讲某品了 于是给弟子示范，告诉他来回数十次的攻洁辩难，并且说： 过去这里面的问题不可能比我讲的更明白了。 
开戒弟子： 道林讲，比汝至，当在某品中。 因示语攻难数十番，云： 旧此中不可复通。 
Yufakai reminded his disciple, "When you arrive, Dao Lin will be lecturing on a certain section of *Xiaopin*." So he gave the disciple a demonstration, telling him of back-and-forth attacks and defenses dozens of times, stating, "*Liaoyin's* questions aren't likely to top mine."
