Shi Yongheng: publicly available information is limited, and the only known work is a single title, The Physician Wu Lien-teh, classified under general biography. Wu Lien-teh is an important figure in the modern history of public health and epidemic prevention in China, and biographies of him generally center on his anti-epidemic practice, medical career, and historical context. In this book, rather than adopting a grand panoramic narrative, the author focuses on a physician's choices and sense of responsibility in turbulent times, making specialized historical facts accessible to general readers. Because verifiable information about the author's background, career, and creative development is lacking, readers should understand his writing orientation through the work itself: using biography to carry medical history and historical memory, and to bring this pioneer of epidemic prevention back to public attention. His writing style and influence await more materials and works to be fully presented.
