《宋史·列传·卷一百一十八》
送给金人的器币礼物，耗费了不少，使者往来之间，使我们坐失士气，可金人还向我们强求我们一定不能依从之事，强制我们以我们必不敢为之谋。像这样最终达不成和议，而只是白白给我们增加烦扰。
器币礼物，所费不赀，使轺往来，坐索士气，而又邀我以必不可从之事，制我以必不敢为之谋，是和卒不成，而徒为此扰扰也。
The utensils and gifts sent to the Jurchen cost a lot, the envoys going back and forth caused us to lose morale, still, the Jurchens kept on forcing us into doing some really unacceptable things, forcing us to do something we definitely wouldn't do. Thus, the peace negotiation could not be reached in the end, it only caused much trouble for us.
