《黄帝内经·素问·五运行大论》
子午年是少阴司天，丑未年是太阴司天，寅申年是少阳司天，卯酉年阳明司天，辰戌年是太阳司天，巳亥年是厥阴司天。 这些，与你以前所论的阴阳不怎么符合，是什么道理呢？
子午之上，少阴主之；丑未之上，太阴主之；寅申之上，少阳主之；卯酉之上，阳明主之；辰戌之上，太阳主之；巳亥之上，厥阴主之。 不合阴阳，其故何也？岐伯曰：是明道也。
The Zi-Wu years are Shaoyin presiding over heaven, the Chou-Wei years are Taiyin presiding over heaven, the Yin-Shen years are Shaoyang presiding over heaven, the Mao-You years are Yangming presiding over heaven, the Chen-Xu years are Taiyang presiding over heaven, the Si-Hai years are Jueyin presiding over heaven. These are not very consistent with the yin-yang of what you have discussed before, what does that mean?
