The graduation thesis requires at least three foreign documents. Can they be written by China people in foreign languages?
I am writing my graduation thesis now, which is basically impossible, because the main purpose is to broaden the thinking and internationalization level of your thesis, so it is best not to do so. I suggest that CNKI find books with Chinese translations of relevant papers, so that you can refer to the Chinese version when writing your papers, but you can refer to books to write English versions. Hehe, kill two birds with one stone.
