Traditional Chinese medicine（TCM） believes that "everything that is tangible is nothing more than yin pathogens scum". As a tangible entity

the tumor cannot restrict and generate yin fluid due to yang deficiency in the body. The fluid thus condenses into sputum

blood stasis and other yin pathogens scum. Based on the theory of "yang transforming into qi

while yin constituting form"

when guiding the clinics

we should first to distinguish the yin and yang. Under the trinity of "differentiation of disease

differentiation of symptoms and differentiation of signs"

we should always support yang and eliminate yin in the appropriate time. Among people with different diseases

treatment methods and people of different constitutions

the weight of yin and yang should be differentiated in detail

and the pathogenesis should be examined in detail by using the method of reinforcing yang

so as not to consume yin and damage the healthy qi. To explore the guiding role of the method of reinforcing healthy qi and dissipating yin in the treatment of clinical syndrome of tumors can lay a foundation for further enriching the TCM pathogenesis theory of tumors and improving the efficacy of differentiation and treatment of tumors.
