You can go to Borui training in Zijingshan, Zhengzhou, which is quite good. Their two majors have always been the best in Henan, and their later services are also good. Teachers are also good in class, passionate, intriguing and personally feel good. You can use the word "zhong" as a reference, mainly depending on your study. Personally, I am quite adapted to their teacher. You can also listen to the lecture before making a decision.
