Hong Feng is an author whose name appears in the field of Chinese popular psychology and self-help writing, though his publicly available personal information remains very limited: his nationality, dates of birth and death, educational background, and professional career are not clearly recorded. Two existing works, Psychological Codes: The Art of Social Psychological Manipulation and The Flexible Application of Thick-Black Business Tactics, offer a glimpse of his writing direction. The former focuses on psychological mechanisms and interpersonal coping in social situations, while the latter applies "thick-black" thinking to business management, discussing strategies and practical techniques for dealing with people in commerce. Both are popular, practical books aimed at general readers, with straightforward language, case-based examples, and an emphasis on applicability; they are commonly classified under applied psychology and inspirational growth. Judging from their subjects, the author attends to the practical use of psychological insight and social strategy in social, workplace, and business settings, favoring summaries of experience and lists of techniques over academic argument. Given the scarcity of verifiable information, his full body of work and personal background await further material, and assessments should be based on the popular, practical orientation shown in the existing books.
