《宋书·志·卷十三》
即使就作为开始移动解释，冬至时太阳在斗宿二十一度，这样大火星黄昏时位于正南方天空中也应在大暑之前，与建申之说哪里有什么关系?
就如始说，冬至日度在斗二十二，则火星之中，当在大暑之前，岂邻建申之限。
Even if we interpret it as just beginning to move, the sun is at the twenty-first degree of Dou at the winter solstice. If Mars is located in the due south of the sky, then it should have been seen before the Dahui. What does it have to do with the theory of Jian Shen?
