Don't worry too much, I don't think it's difficult. I just passed the exam, and it's still good. I'm from Yunnan, and we attended a simulation lecture. Kunming, Yunnan, talks about "the sum of the inner angles of polygons" 15 minutes, and then the examiner asks questions for 5 minutes. The examiner asked two questions, generally about teachers, education and the development of education, as long as you usually pay attention to this aspect.
