Public information about Yu Yan is limited; currently only one work by this author is known, Qian Sanqiang: From Niu to Ai. The book falls under the general category of biography and takes the outstanding Chinese scientist Qian Sanqiang as its subject, narrating his life course and scientific path. Judging from the title “From Niu to Ai,” the author seems to use this symbolic phrase to sketch a certain aspect of the subject’s inner world, so that readers may appreciate his character and sentiments in addition to learning about his life and achievements. The book follows the approach of a personal biography, combining historical materials with narrative, and adopts plain language to introduce this scientist’s experiences and contributions to general readers. Because the available information is very limited, Yu Yan’s own life, identity, and other writings cannot be ascertained at present, and the author’s writing style and academic background await further materials for evaluation.
