Liu Yang is an author with two works held in the library collection, though public information about him is limited; his nationality, dates of birth and death, and English name are not recorded. Judging from the existing works, his writing spans two rather distant fields: one is the popular-science title Virus Planet, and the other is Short Video and Livestream E-commerce (MOOC Edition), a work oriented toward examinations and practical application. This range suggests that he is able to handle both science popularization for general readers and practical content related to digital business and course-based teaching. In his popular-science writing, the emphasis is on presenting scientific topics in an accessible way and helping ordinary readers understand specialized concepts such as viruses; in his practical works, he stays closer to study and examination contexts and serves specific learning needs. Because biographical information is lacking, no further introduction to his background or identity can be given here, and readers may turn to the two works themselves to understand his writing orientation and range of interests.
