Certification by the mainland Ministry of Education is voluntary, not compulsory. For example, when students come back to start their own companies or go to family businesses, they don't need certification, but they need certification for students who want to take the civil service and public institution exams. Certification requires money within 400 yuan, some places charge 360 yuan, and some places charge 380 yuan. 1 to 2 months' certification time is enough to get the certification certificate.
The mainland implements the dual certificate system: qualified graduates need a degree certificate and a diploma. However, both Hong Kong and Macao Special Administrative Regions implement a single internship certificate system, and qualified graduates have only one degree certificate.
This degree certificate is equivalent to two certificates in Chinese mainland!
Just like 100 Hong Kong dollars and 80 RMB have the same communication ability in the same place, there is no difference.
Besides, Hong Kong's universities rank weakly in the top 200 in the world, and how many schools in Chinese mainland are in the top 200, and then the top 200 universities are basically famous schools. Besides, in terms of academic ranking alone, Hong Kong schools far exceed 99% of universities in Chinese mainland. We are basically mainlanders, so we naturally know how much cheaper Chinese mainland's university area, enrollment and library scale are than Hong Kong's!
In addition, once again, there is no difference between a research-oriented master and a teaching-oriented master. There is no one who has higher gold content than anyone else, but the purpose of setting is inconsistent with the enrollment target.
