His comments came after a local newspaper reported that some school libraries had removed books from their shelves, citing security concerns.
Some schools have also earlier complained about the lack of specific guidance from the Office of Education on vetting reading materials, admitting it has led to self-censorship, the newspaper reported.
Speaking to reporters on Monday, Yeung said schools should choose books that are age-appropriate for students and with reference to teaching needs, while schools should also ensure that their libraries are free of books. likely to compromise national security.
He said the Office for Education had issued a clear directive to schools and asked them to seek help from the office if in doubt.
