《明史·志·卷二十七》
而夏言又上疏议论柿祭德祖有四点可疑，而且说现在规定太祖为太庙中的始祖，不是帝王建始祖庙的始祖。
而言复疏论禘德祖有四可疑，且言今所定太祖为太庙中之始祖，非王者立始祖庙之始祖。
However, Xia Yan further submitted a memorial criticizing the柿祭德祖, stating four major points of suspicion and also stating that the current regulation that places Taizu as the first ancestor in the imperial Tai Temple is not the standard example of an emperor building an ancestral temple for a first ancestor.
