Public information about Tong Laisheng is limited; all that is currently known is that the author has one work in the field of industrial technology, Research, Development and Application Practice of Medium- and Low-Speed Maglev Trains. The title indicates that the book focuses on the specialized area of medium- and low-speed maglev transportation, centering on train development and engineering application practice, and belongs to professional writing on rail transit and equipment manufacturing. Works of this kind generally require the author to have accumulated knowledge in vehicle engineering, traction control, or line systems, and tend to combine technical principles, scheme design, and practical cases, primarily for industry technicians, researchers, and students and teachers in related fields. Because biographical details are unavailable, the author's educational background, affiliation, and research direction cannot be confirmed. Readers may therefore focus on the work itself: it offers a practical record of medium- and low-speed maglev technology moving from development to application, and opens a window for readers interested in the diversification of urban rail transit to learn about this technical route.
