Abstract：Bronchial asthma is a common respiratory disease in children，with recurrent relapses and a protracted course， severely impacting children's physical and mental health. This paper centers on the theory of "nourishing or dispersing based on preference or dislike of lung" in Huang Di Nei Jing （The Yellow Emperor's Inner Classic），which posits that the main pathogenesis of asthma is located in the lung，with disordered qi movement and upward-reversed lung qi being a consistent feature throughout the whole process. Director LIN Jiwen，based on children's physiological and pathological characteristics，views asthma as a condition with deficiency in the root and excess in the manifestation. During the acute phase，the manifestation of lung should be treated first. Once the symptoms alleviated，both root and manifestation should be treated concurrently. Throughout the therapeutic process， LIN emphasizes the importance of regulating qi dynamics，using bitter，sour，and pungent medicines to descend and consolidate lung qi. This approach embodies the theoretical principles of "nourishing or dispersing based on preference or dislike of lung".
