Here I borrow the concept of DNA to point out that

the innate way of thinking leads to a huge difference between 
Traditional Chinese Medicine (TCM) and Western medicine, 
which is the epistemology of understanding objective things.  

Western medicine adopts the "內外法", starting from a local link 
inside the research object, and gradually deepening and expanding
layer by layer until the internal laws of the research object 
are more clarified. 

However, TCM uses the "外內法" to infer its internal laws 
through the external state of the research object.

我們的主流醫學是現代醫學, 大部分人釆用, 乃順理成章的事兒. 少數人了解中醫, 以中醫的某些優勢維護健康, 那是他們的 benefit.
