Chen' is originally a kind of prophecy that predicted the good or ill luck of the human world in the name of deities. 'Wei' (weft) opposite to 'Jing'(wrap),refers to those works written by alchemized Confucian Scholars and Confucian alchemists who interpreted Confucian canons according to the concepts of theology and superstition. 'Chen' and 'Wei' had once merged in Western and Eastern Han dynasties and became the popular trend of 'Chen Wei' Thought. The books about charms, omens, etc. were always named 'Chen Wei' or 'Chen' in ancient times. So 'Chen' and 'Wei' were usually mentioned in the same breath or were regarded as one thing with different names by subsequent generations. This article, which investigates the history of the emergence and development of 'Chen' and 'Wei', argues that though 'Chen' and 'Wei' are related to each other, they are different from each other, the two being different concepts.
