What is disease-free? According to the common understanding of modern people, the future is uncertain, and of course, future diseases are also uncertain. They are diseases that may or may not exist in the future, with a dual ambiguity. From the essence of the Inner Canon, the term 'wei' here is definite and carries a singular inevitability. 'Wei' is the 'Wei' after the Earth branch's' noon ', representing time. With the rotation and revolution of the Earth, it is the moment when the sun's rays at noon will inevitably come and shine, representing the future, opposite to' already '.
什么是未病？按照现代人惯有的理解，未来是不确定的，未来的病当然也是不确定的，是以后“可能有”也“可能不会有”的病，存在着双重的模糊性。从《内经》的本旨来解，这里的“未”是确定的，带有单一的必然性。“未”是地支“午”后之“未”，代表时间，随着地球的自转与公转，是正午的太阳光线必然要光临照射的时刻，代表未来，与“已”相对。
