A double degree usually refers to a double bachelor's degree, which means that on the basis of obtaining the first bachelor's degree, you study another subject full-time, and after meeting the requirements set by a university, you are awarded a second bachelor's degree. Different from the second bachelor's degree, the minor of the second degree is to study the minor of this major and another professional degree course at the same time in the undergraduate study stage, and obtain the minor bachelor's degree of another subject at the same time after meeting the specified requirements.

The biggest difference between double degree, minor double degree and second degree (double degree) lies in the issuance of certificates. The bachelor's degree certificate is issued by the examiner after the completion of the double degree and minor degree, and the graduation certificate and bachelor's degree certificate are issued by the examiner after the completion of the second degree (double degree).

The graduation certificate indicates the minor major in the first professional certificate, that is, two majors. Most minor majors are issued by schools, but the certificate number is not unified by the Ministry of Education, and the minor diploma is not registered electronically.
