Huang Di Nei Jing (《黄帝内经》Yellow Emperor’s Inner Canon) is the earliest and most important written work of Traditional Chinese Medicine. It was compiled over 2,200 years ago during the Warring States period (475-221 BC) and is regarded as the fundamental and most representative medical text. The version nominated for inscription in the Memory of the World Register was printed and published by Hu’s Gulin Sanctum in 1339 using the woodblock-printing technique. It is the earliest and the best-preserved version of its kind now extant
