2. Email contact. Like the telephone, the tutor's email is usually posted on the campus network. The advantages of email contact are low cost and large amount of information. For example, candidates can introduce themselves to the tutor in detail by email, such as research interests, hobbies, specialties and so on. In this way, the tutor can have a more comprehensive grasp of the candidates.
3. Face-to-face communication. The advantage of this method is that it is intuitive and informative. With its help, there will be a deep understanding between candidates and tutors. If the tutor praises the candidate, it will undoubtedly increase the chances of the candidate's success, and some tutors will even designate the candidate.
