Because a bachelor's degree is a manifestation of research ability, it must be accompanied by a bachelor's degree certificate, that is to say, a bachelor's degree certificate can only have a degree certificate, but there must be no degree certificate without a bachelor's degree certificate, so there is no need to stamp the school seal on the degree certificate. This is one; Second, the degree certificate is issued by the degree committee, not by the school, because only the degree committee represents the recognition of this ability, and the school itself cannot carry out this kind of certification, so it can only be stamped with the name of the chairman of the degree committee.
popularization: those who have obtained a bachelor's degree certificate do not necessarily have a bachelor's degree certificate, but those who have a bachelor's degree certificate must have a bachelor's degree certificate. But this only applies to bachelor's degree, not master's degree, because master's degree has on-the-job entrance examination, that is, only master's degree certificate has no master's diploma. This is also the case for doctors, but a bachelor's degree is a special case. Those with a bachelor's degree will definitely have a bachelor's degree certificate.
