《史记·七十列传·儒林列传》
所以自汉朝开国以来历经五朝，期间只有董仲舒对《春秋》最为精通，名望甚高，他师承传授的是《春秋》公羊学。
故汉兴至于五世之间，唯董仲舒名为明於春秋，其传公羊氏也。
Therefore, since the founding of the Han Dynasty, there have been only five dynasties. During this period, only Dong Zhongshu was the most proficient in the "Spring and Autumn Annals" and had a high reputation. He inherited the Gongyang school of the "Spring and Autumn Annals".
