In terms of quality, Beijing ranks first, followed by Shanghai. But Shanghai is definitely not bad ~ you are a friend of Zhejiang, recommend Shanghai ~! The teachers in the TOEFL class are almost the same, and there are no specific teachers with specific classes. However, you can find classes taught by star teachers on the website of Shanghai New Oriental School. Wu Peng's reading and Lin Yan's oral English are very good! My personal favorite is Jiang Qi, who teaches composition. In a word, she is smart!
