With nearly 21 years of medical practice and accumulated clinical experience, I have developed a strong proficiency in diagnosing and treating both common and complex respiratory diseases. In particular, I have extensive experience in interstitial lung disease, pulmonary fibrosis, sarcoidosis, pulmonary infections, chronic obstructive pulmonary disease, asthma, respiratory failure, and mechanical ventilation. I specialize in the diagnosis and management of various difficult and complicated cases. Not only do I possess substantial clinical experience in the diagnosis and differential diagnosis of diffuse lung diseases, but I have also undertaken and participated in over ten major research projects in this field. I have published more than twenty academic papers, co-authored two monographs, and have achieved nationally leading scientific and technological advancements and awards in the study of interstitial lung disease. I have also participated in numerous domestic academic activities for exchange, learning, and invited lectures. My expertise in the diagnosis and treatment of interstitial lung disease is at the leading level in China.
