It is not difficult to get a diploma. You can get a diploma by paying tuition according to the graduation time of 3 or 4 years.
Diploma is also a university diploma recognized by the state, but it seems to be marked with continuing education.
Because continuing education is subject to different places and different forms of education (videos are only taught on weekends every week or night), many people do not quite recognize this diploma compared with full-time university study time.
Personally, I think it may be different from full-time except for large institutions, enterprises and institutions.
Most small enterprises should be different, but the ability is the most important.
