Zhou Shuai of Gaotuban is so powerful. My math class in Gaotu class was taught by Zhou Shuai, and Shuai Shuai was admitted to Peking University as the top student in the college entrance examination. At first, the vivid image of the teacher's lecture made my blood boil. Yesterday afternoon, I just listened to Mr. Zhou Shuai's class. As always, good, amazing! I also listened to teacher Shuai Shuai's story, which was very inspiring. Thank you very much Shuai Shuai for sharing! Every time I listen to his class, I feel that I can meet him in my sophomore year. I am really lucky, I saved my math and slowly changed my view on online classes.
