I only know Hushi University. There are many graduate education institutions now. As far as I know, only two institutions are relatively large, strong and stable: Du Wen and Navigation. Both schools are located in Shanghai University in Times Guanghua Building.

Personally, I think Du Wen's English is strong and his politics is strong in sailing. The female teacher surnamed Zhang (whose name has been forgotten) who is engaged in maritime politics has a good philosophy. Anyway, the students in our class who reported sailing in the past are good at politics, and personally feel that Du Wen is better in English. There are teachers like Xu Zhan, who are always passionate about learning English. And found that there are so many tricks in learning. Other teachers are similar, and some teachers are part-time in these two institutions. (To tell the truth, other postgraduate institutions are basically not well-known in Hushi, and there seems to be a final rival in Wenhai postgraduate promotion, but these two established institutions that have been rooted in Hushi for many years have been squeezed out, hehe)

This is my opinion, please contact me if you have any questions ~
