The refresher course itself is not a regular course in the national education system, so only the certificate of completion is issued. Moreover, this certificate of completion plays a certain role in the circle, but it is not big. After all, it is not easy to find an undergraduate job graduated from Nortel.

In fact, you can still get in touch with many teachers when you go to the advanced class, and what the professor gives you will definitely be useful. Of course, the quality of refresher courses is uneven. I remember that Chen was not an orthodox Chinese opera student in the original Chinese opera teacher training class, and the Chinese opera star wall was absent, but his grades were higher than many students.
