Neijing is traditional Chinese medicine; it encompasses all the central tenets of Chinese medicine practised today. Neijing zhiyao, in two volumes, compiled by Li Zhong-zi of the Ming dynasty, was carefully proof-read by Xue Sheng-bai of the Qing dynasty. Among the hundred or so annotated editions of Neijing Suwen and Lingshu that appeared in different formats and styles in previous generations, only Neijing zhiyao compiled by Mr. Li Nian-er of the Ming dynasty is the most succinct but pithy. —— from Sibu Zonglu Yiyaobian 《內經知要》二卷,明．李中梓輯、清．薛生白重校。嘗考內經素問、靈樞,歷代註釋者不下百家,體裁各各不同。惟明．李念莪先生所輯《內經知要》最為簡當。——《四部總錄醫藥編》
