《汉书·传·游侠传》
张竦学问渊博，理事通达，以清廉节俭自我约束，而陈遵却放纵而不拘小节，然二人操守品行虽然不同，但互相之间却很亲近友爱，哀帝末年时，他们都已很具名望，成为了后进人士中的佼佼者。
竦博学通达，以廉俭自守，而遵放纵不拘，操行虽异，然相亲友，哀帝之末俱著名字，为后进冠。
Zhang Song was erudite and well-informed, clear and impartial in handling affairs, and self-disciplined in practicing economy and integrity. Chen Zun, on the other hand, was indulgent and extravagant in style, and indiscreet to details. Despite their different virtues, they were close friends and showed love for each other. They gained wide fame in the declining years of Emperor Ai and became outstanding figures among the younger generation.
