Abstract： This paper summarizes the characteristics of syndrome differentiation and treatment as well as medication rules of Prof. CHENG in the treatment of chronic heart failure. Prof. CHENG believes that chronic heart failure is mostly a syndrome of deficiency in origin and excess in superficiality， whose most common pathogenesis is disturbance of qi transformation and internal generation of stasis and water. Its treatment should be focused on warming and supplementing yang qi to restore the qi transformation. Chinese medicine practitioners should understand the mechanism of pathogenesis between different syndromes as a whole， take Zhengwu tang as the main prescription to warm and supplement yang qi， invigorate blood and promote urination， and soothe triple energizers， and should consider different people and how to reinforce healthy qi and dispel pathogen.
