At present, there are 68 colleges and universities in China that can set up online education colleges, generally China Renmin University, Beijing Foreign Studies University, Sun Yat-sen University and other well-known universities.
As long as it is recognized by the state and the academic qualifications are recognized by the Ministry of Education, there is no need to worry about this.
As for whether you can learn something, it depends on the details:
I am studying in Beijing Foreign Studies University, but my major is English, which is relatively difficult. It is said that the major of economic management is easy, and I can do my homework. My understanding of online education is that time and place are free, and the teachers who teach are also famous teachers, but the teachers are better than the general self-study training and senior high school entrance examination institutions. It is more suitable for busy students to study. The exam is not too difficult. It's relatively easy to get a degree when you get into high school and take the self-taught exam.
But online education has high self-control ability. In addition, because there is no face-to-face teaching, questions can only be asked through forums, and knowledge update is not timely. I think they also have a thing called VOB, which is similar to the network conference system, but not as direct as face-to-face teaching.
