《宋史·列传·卷二百三十四》
先前，张邦昌力主和议，不料自己成为人质，等动身时，就请求钦宗亲署御批不改变割地和议的决定，没答应他；又请求给河北发诏书，也没答应。
初，邦昌力主和议，不意身自为质，及行，乃要钦宗署御批无变割地议，不许；又请以玺书付河北，亦不许。
Previously, Zhang Bangchang strongly advocated for peace negotiations. Unexpectedly, he became a hostage. When he was about to leave, he asked Emperor Qinzong to personally sign an imperial edict that would not change the decision to cede territory for peace. Emperor Qinzong did not agree. Zhang Bangchang also asked for an imperial edict to be issued to Hebei, which Emperor Qinzong also did not agree to.
