Sorry, I had a holiday and didn't see your question in time. What needs to be clear is: first of all, bookstores can't apply for library cards. Bookstores are commercial organizations and will not provide book lending services. Secondly, I am not from Xiamen, but I have been to Xiamen Library (a beautiful and comfortable place). Specific answers and phone numbers can be found in "Xiamen Library" through Google and Baidu. In addition, some universities in Xiamen can also try to contact, and it is possible to apply for library cards for teachers and students who are not in school. Academic quality and information quality of university libraries are generally higher than those of ordinary public libraries.
