Qin Yingbo, about whom public information is limited, is known only as a Chinese author. The library holds one work by this author: A Concise Tutorial on Web Front-End Development (HTML+CSS+JavaScript+jQuery), commonly classified under programming and design. Judging from the title and category, the book is aimed at beginners in front-end development and covers four foundational technologies: HTML, CSS, JavaScript, and jQuery. It appears to be a practical, clearly structured tutorial in which the author organizes knowledge and explains examples in a concise style intended to lower the barrier for newcomers. Since no reliable records of birth and death dates, education, or career are available, no speculation is made here; any assessment of the author's writing can rest only on the subject matter and positioning of this single work, and further details may be added if more information becomes available.
