《资治通鉴·后梁纪·后梁纪五》
在杨刘城失守以前，后梁租庸使、户部尚书赵岩曾对后梁帝说： 陛下即位以来，还没有去南郊祭天，议论这件事的人认为陛下和诸侯没什么两样，被四方所轻视。
先是，租庸使、户部尚书赵岩言于帝曰： 陛下践祚以来，尚未南郊，议者以为无异籓侯，为四方所轻。
Before Yang Liu city fell, the Later Liang rental-corvee envoy, the Minister of the Ministry of Households, Zhao Yan, once said to the Later Liang Emperor: Your Majesty has not gone to the southern suburbs to worship heaven since your accession to the throne. People who discuss this matter believe that Your Majesty is no different from the feudal lords and is despised by all sides.
