有醫者， 自稱善外科。一裨將陣回，中流矢，深入膜，延使治。乃持并州剪，剪去矢官，跪而請酬。裨將曰：“鏃在膜內須亟治。”醫曰：“此內科之事，不意並責我。”裨將曰：“嗚呼，世直有如是欺詐之徒。”

A surgeon boasted of his skill in external surgery. Once, a deputy general returned from battle with an arrow shot him and went into his deep muscle. He asked the surgeon for treatment. The surgeon used a pair of scissors produced in Bing County to cut off the arrow and then knelt for remuneration. The deputy general said, "You have not taken care of the arrowhead inside the fresh." The surgeon replied, "That is the business of internal physicians, so you should not ask me to do it." The deputy general exclaimed, "How come there is an imposter like you in this world."
