Recommendation letters must be objective and fair. They must not be formalistic or empty in content. They must be consistent with the applicant’s other materials (such as transcripts). Recommendation letters should also pay attention to format, grammar, etc. The format of a recommendation letter is basically the same as a general letter. It includes the letterhead, date of sending the letter, recipient's name, title, body, title at the end of the letter, signature, recommender's name, professional title and work unit, etc. However, the recommendation letter should also focus on the following aspects:

1. In order to facilitate the school’s review, the full name of the recommended person must be mentioned. The identity of the recommender is not important. Of course, it is good if you ask an academician to write it, but the most important thing is to convince the admissions committee that the recommender truly knows the person being recommended.

2. You must explain the period of acquaintance with the recommended person (when you started to know each other or how long you have known each other), the degree of acquaintance (occasional meeting or close contact) and the relationship (teacher-student relationship, superior-subordinate relationship, colleague, etc.) ).

3. Introduction and evaluation of the recommendee’s strengths, which is the core of the recommendation letter. Mainly include the recommender's talent, academic performance, research ability, work experience, learning spirit, organizational ability, conduct and personality. Note that the rhetoric should echo other application materials such as transcripts, award certificates, etc., and avoid contradictions that may lead to misunderstanding. No one is perfect, so their shortcomings should also be mentioned in order to be fair and objective. This is best illustrated by examples. What professors want is not a perfect person, but just a student, an average but good enough student.

4. The recommender’s attitude must be stated, whether it is a strong recommendation or a reservation.

5. It is best to ask the recommender to sign on the seal of the envelope to ensure its authenticity. It is best to fill in "NO" in the column "Do you reserve the right to review letters of recommendation in the future?"
