Library major is not a "hot" major in the traditional sense, so at present, only Sun Yat-sen University in Guangdong has this major, and it has been in CUHK for nearly 30 years (if counted from the reform and opening up). However, due to enrollment and employment, this major enrolls students every other year in previous years. That is to say, if it enrolled students last year and stopped this year, it is not clear whether the policy has changed this year. You can call and ask. The website of Sun Yat-sen University is www.zsu.edu.cn. Good luck!
