Each college is responsible for the specific certification work, and graduate students can choose the appropriate way to sign and receive certificates according to the requirements of the college notice and their own actual situation.
If the certificate is lost after mailing, it will not be possible to reissue the original, but only the academic qualifications and degree certificates. Graduate students should apply carefully according to their own actual situation. In view of the current unstable express delivery, there is no need to mail it.
