Abstract：This article introduces Professor HONG Minli's clinical experience in treating chronic cough. Professor HONG Minli believes that deficiency of healthy qi and spleen-stomach deficiency are the fundamental causes of recurrent chronic cough， while wind-cold lingering in the lung， pathogenic factors stagnating in the Shaoyang， phlegm-fluid retention，and damp-heat accumulation in the lung are the main pathogenic mechanisms of chronic cough. In clinical practice，treatment is administered based on syndrome differentiation，focusing on reinforcing healthy qi and releasing the exterior，harmonizing the Shaoyang，warming and dissolving phlegm-fluid，clearing and draining dampheat， and regulating and tonifying the spleen and stomach.
