《旧唐书·列传·卷七十九》
黄河洛水一带长期遭受战乱，村镇成了废墟，张延赏带头率领部下勤奋努力，政务崇尚精简朴素，疏通河流渠道，修筑宫殿祠堂，几年之间流民归附，城镇都恢复了，皇帝下诏书褒奖他。
河洛久当兵冲，闾井丘墟，延赏勤身率下，政尚简约，疏导河渠，修筑宫庙，数年间流庸归附，邦畿复完，诏书褒美焉。
The area along the Yellow River and the Luo River had been ravaged by war for a long time, and the villages and towns had become ruins. Zhang Yanshang took the lead in leading his subordinates to work diligently and energetically. In government affairs, he advocated simplicity and frugality, dredging rivers and canals, building palaces and temples. Within a few years, refugees returned and the towns recovered. The emperor issued an imperial edict to commend him.
