《宋史·列传·卷二百三十四》
张邦昌刚即位，应推恩四方，因道路阻隔，先在京城大赦，选郎官为四方密谕使。
邦昌以嗣位之初，宜推恩四方，以道阻先赦京城，选郎官为四方密谕使。
As soon as Zhang Bangchang ascended the throne, he should have extended his favor to all sides, but because the road was blocked, he first granted amnesty in the capital and selected Langguan as the secret envoy to all sides.
