The history in past two thousand years proves that innovation is the primary driving force behind sustainable development of traditional Chinese medicine（ TCM）. The form of theoretical system of TCM was an original construction. After that

clinical medicine became independent and divided

and medical practitioners of the past dynasties carried forward the theories of Inner Canon of Yellow Emperor（ 《黄帝内经》） and ZHANG Zhongjing’s therapeutic methods. Especially

the medical schools in Song and Yuan Dynasties came out and the epidemic febrile disease theory established

and the innovative dynamism of TCM had strengthened. And the prerequisite of innovation and development is drawing on the achievements of related disciplines in all ages. During the past hundreds of years

the manifestations of TCM’ s lack of innovation are the research direction having deviated from the theories in Inner Canon of Yellow Emperor and the technology having been behind the times. Combination between four diagnostic methods and modern technologies might be the first innovation in feasible area. Then systematic researches on yinyang

qi and blood

essence and fluid which connect with "visceral element"and "manifestation element"will possibly be the new method of viscera-state doctrine.
