《资治通鉴·汉纪·汉纪三十四》
刘秀因为窦融很讲信义，清楚地表明了立场，更加嘉奖他。下令整修窦融父亲的坟墓，用牛羊猪各一祭祀，屡次派出轻装使者，送给窦融四方进贡的珍奇食物。
帝以融信效著明，益嘉之，修理融父坟墓，祠以太牢，数驰轻使，致遗四方珍羞。
Liu Xiu commended Dou Rong even more because he kept his words and clarified his stand. He ordered Dou Rong's father's tomb to be renovated and offered sacrifices with a cow, a sheep, and a pig. He repeatedly sent envoys with light armors to deliver exotic foods from all over the country to Dou Rong.
