Nan Jing (Chinese medicine)

Nan Jing (難經 , Classic of Difficult Issues), also known as the Classic of Difficulties or Difficult Classic, is a seminal text in Traditional Chinese Medicine (TCM). It is considered one of the ancient Chinese medical texts, following the Huangdi Neijing (Yellow Emperor's Inner Canon), and focuses on the theory of acupuncture, diagnosis, and treatment. The Nan Jing is attributed to Bian Que, a legendary physician from the Warring States period (475-221 BCE), although the actual authorship and date of composition are subjects of scholarly debate, with most estimates placing its compilation around the Han Dynasty (206 BCE – 220 CE).
