郑毅

Zheng Yi is an author about whom limited public information is available; he is currently known for two works, one in medicine and one in management, written for practical readers in different fields. Systemic Vasculitis (2nd Edition) is a medical professional book on systemic vasculitis, and the second edition indicates that the content has been revised and expanded, making it suitable for clinicians and those working in related research. Enterprise Digital Transformation: Theory and Upgrade Solutions for Real-Economy Enterprises turns to business management, discussing the theoretical framework and upgrade paths for real-economy enterprises pursuing digital transformation, with a clear emphasis on practical solutions. The two works span quite different subjects—one focused on organizing knowledge about disease diagnosis and treatment, the other on analyzing practical business problems and proposing responses. What they share is an attention to concrete issues, serving readers through systematic organization and actionable approaches. Because biographical information is lacking, judgments about his writing style and influence can only rest on the works themselves and await further material.
