How is Qi written in ancient medical books?

The three writing methods and meanings of Qi in ancient medical books are as follows:

(1) The word "Qi": This is the word "Qi" in ancient Chinese, with the word "无" above. It’s the ancient word for 无. The word "灬" below is a variant of fire. The ancient Taoist Alchemy Book mentions "Qi", and the word "Qi" is often used. It can also be said that the absence of fire is called "qi".

Taoist thought and scholarship are always inseparable from ancient Chinese magic, especially the five elements, heavenly stems, earthly branches and other nomenclature and terms. Among the five elements, the heart belongs to "fire", so if there is no fire, it is called "qi". To achieve a state of quiet rest and mind, without thoughts or worries, is the state of true "qi".

(2) The word "qi": It is also the word "qi" in ancient Chinese. Most of the Chinese characters and seal scripts use this word "qi". To put it more emphatically, the word "qi" represents the atmosphere of nature.

(3) The word "qi": It is a commonly used word for qi in later generations, but according to the concepts of ancient Taoism and ancient Chinese medicine, this is the "qi" that has the function of breathing life after people eat rice. ".

"Qi" has a very prominent influence in traditional Chinese culture. Not knowing "Qi" means not understanding the roots of traditional Chinese culture. It is said that without "Qi", there is no "Tao"; if there is "Qi", there must be "Tao". It reflects the great wisdom of traditional Chinese culture and the worldview of the ancient Chinese sages. Mencius said: "I am good at cultivating my awe-inspiring Qi."

"Qi" not only refers to the material origin that forms all things in nature, but is equivalent to the modern scientific term "energy"; and the operation of "Qi" embodies the universal principles of nature. The wisdom that exists is unparalleled.
