Professional diplomas jointly trained by two universities are usually awarded by undergraduate schools. The joint training of students is only in different training places, and the others are the same as those of undergraduate colleges. Joint training means cooperation between colleges and universities, which provide academic qualifications and provide environment. After graduation, candidates have obtained the graduation certificate and bachelor's degree certificate of undergraduate colleges, and have a full-time undergraduate degree. Undergraduate universities jointly run schools, and the undergraduate diploma means holding the undergraduate diploma and degree certificate. When taking the postgraduate entrance examination, it is easier to be admitted to a postgraduate school than to hold a diploma jointly run by an undergraduate university and a junior college.
