Public libraries in Hong Kong can only borrow books if they apply for a library card with a Hong Kong identity card. But you can go to the public library in Central Hong Kong to see if there are any books you want, because the books in this library will have reference books from other universities, and you can also search from the library computer.
The price of photocopying service varies from university to university, ranging from 0.2 yuan to 0.5 yuan.
Photocopying in other places in Hong Kong, such as stationery stores, requires at least 1 yuan to 1.5 yuan. )
Because everyone knows what intellectual property is, no one in Hong Kong will photocopy a book for you. Even if it is only a unit of a book, it is a violation of copyright. Even a small number of textbooks, if they are elements of textbooks, can also constitute copyright infringement. So if you really go to Hong Kong to collect information, there will be such obstacles.
