《黄帝内经·素问·六节藏象论》
岐伯说：春克长夏，长夏克冬，冬克夏，夏克秋，秋克春，这就是时令根据五行规律而互相克制的情况。
岐伯曰：春胜长夏，长夏胜冬，冬胜夏，夏胜秋，秋胜春，所谓得五行时之胜，各以气命其脏。
Qi Bo said: Spring restrains Long Summer, Long Summer restrains Winter, Winter restrains Summer, Summer restrains Autumn, Autumn restrains Spring. This is the situation in which the seasons restrain each other according to the law of the five elements.
