Zhang Lingling: publicly available information is limited. She is known in this library for two works, both centered on the teaching of engineering drawing: Engineering Drawing (2nd Edition) and the companion Engineering Drawing Exercise Book. Judging from the titles and their usual classification, her writing falls in the fields of industrial technology and examination materials, aimed at the needs of engineering drawing courses in engineering colleges and balancing theoretical explanation with practice. The second edition indicates a revised textbook, while the exercise book is designed to be used alongside the main text so that readers can practice as they learn and check their grasp of the material. The available information is not sufficient to describe her education, positions, or professional experience, so a biographical account would not be appropriate. Overall, she is known for compiling textbooks and study aids for classroom and self-study use, and her works have a practical role in basic engineering drawing instruction.
