In your case, I recommend the CIO class of Peking University. The degree of specialization is relatively high in courses, systems and teachers. Tsinghua's technical director class is too focused on management, but IT is not IT management. The words of the Chinese Academy of Sciences are mainly that the teachers are relatively single.
And as far as the authority of the certificate is concerned, it is also a CIO class of Peking University. It is a course sponsored by the Information Management Department of Peking University, and officially put on record by Peking University.
Price comparison, these three grades are similar. 20 thousand to 30 thousand I don't know if you can take it personally. I suggest you apply for public training ~ ~
Most other classes are run by IT vendors. Not so pure education. Not very desirable.
If you want to go to class, choosing a better class is good for your future. Not only courses, but also online platforms are very important. Not only teachers, but also students of CIO.
That's all the suggestions. The detailed information of CIO class in Peking University should be easy to find, and you can find it yourself. Check Baidu, or go to the website of Peking University Information Management Department.
