Very good. Teacher Zhang Xiaobo is a Chinese teacher from Yancheng Middle School. He has been on the job for more than 30 years. He is good at fully applying literacy teaching in specific contexts and allowing students to consolidate their understanding. At the same time, on the basis of literacy and writing, students can read the text correctly and fluently. Teacher Zhang Xiaobo's classroom teaching truly "returns" the classroom to the students and stimulates students' interest in learning. The lectures are very good.
