Abstract： The diagnosis and treatment of children with persistent cough is difficult. Director CHEN Hui， based on the ascending， descending， exiting and entering of qi movement in Chinese medicine theory and combined with clinical practice，believes that the common pathogenesis of persistent cough in children which has nothing to do with emotion，is related to the lung，spleen，stomach and triple energizers. Because the function of these zang-fu organs is closely related to the qi movement， Chen summarizes the method of regulating qi movement to treat persistent cough， and on this basis， Chen concludes the lung cough，spleen cough，stomach cough and triple energizers cough. After syndrome differentiation and treatment，the purpose of regulating qi movement is finally achieved so as to treat persistent cough in children effectively in clinical practice.
