When the article was published, the first author was a student and the second author was a tutor. Such an article counts as both a student and a tutor. In fact, in many colleges and universities in the United States, tutors generally don't be the first author unless they do most of the work of the article. However, in China, many tutors are so bad that they make their own articles written by students. Therefore, CUHK's professors are still very kind and have academic self-restraint.

Therefore, in view of the existence of this bad character, there is a stipulation that the first author of the tutor and the second author of the student are also the achievements of the students and can be used for graduation.
