《黄帝内经·素问·调经论》
黄帝说：先生说虚证和实证共有十种，都是发生于五脏，但五脏只有五条经脉，而十二经脉，每经都能发生疾病，先生为什么只单独谈了五脏？
帝曰：夫子言虚实者有十，生于五脏，五脏五脉耳。夫十二经脉皆生其病，今夫子独言五脏。
The Yellow Emperor said: You said that there are ten types of deficiency and excess syndromes, all of which occur in the five Zang organs, but the five Zang organs have only five meridians, and the twelve meridians can all cause diseases, so why did you only talk about the five Zang organs?
