Zheng Hongbin: public information is limited, and only the Chinese name and two medical works are currently known. The representative works are The Medical Classics School and Immortal Grand Master Lou Ying: Academic Thought and Clinical Application, both in the field of traditional Chinese medicine. Judging from their subjects, Zheng Hongbin focuses on sorting out the academic schools of Chinese medicine and organizing the thought of physicians: the former presumably unfolds around the Medical Classics School as a line of academic transmission in Chinese medicine, while the latter takes the Ming dynasty physician Lou Ying as its subject and examines his academic thought and clinical application. Taken together, the two books show a writing approach weighted toward textual sources and scholarly exposition, using school transmission and individual physician case studies as entry points to serve research on the academic history and clinical experience of Chinese medicine. Because biographical information is scarce, the author's nationality, dates of birth and death, education, and positions cannot be confirmed and are not speculated upon here; only the subjects and orientation of the known works are briefly introduced.
