Most of them are professors in mathematics departments of several famous universities in Shanghai. A few days ago, my classmate's classmate was studying in Northwestern Polytechnical University, and his senior math teacher was the one who came up with the most embarrassing math problem when they saved the college entrance examination. Anyway, I only know that Professor Zhou Hong from the Chinese Language and Literature Department of China Normal University is the head of the Chinese composition marking group of the college entrance examination. I think the teachers in China Normal University are more reliable. After all, they are engaged in education for reference only.
