《资治通鉴·后周纪·后周纪五》
世宗说： 以前奉命出使的人，索求没个满足，使得四方之人轻视朝廷命令。爱卿能够如此，非常好；然而别人既已将此馈赠爱卿，爱卿自可取走。 
帝曰： 曏之奉使者，乞丐无厌，使四方轻朝命，卿能如是，甚善。然彼以遗卿，卿自取之。 
Emperor Shizong said, "Previously, the envoys asked for things and were never satisfied, which made the people of the world look down on the imperial orders. It is very good that Your Majesty can do this; however, since others have already given these gifts to Your Majesty, Your Majesty can take them."
