The teachers in the re-reading class of the college entrance examination of Feiyue Education are all on-the-job teachers, all of whom are young and middle-aged teachers who have graduated from demonstration major, bachelor degree or above, and engaged in the education industry for at least three years. They are very active in class and are very popular with children born after 90. They don't want to be like some retired teachers, whose ability to accept new things is too poor, and the old teachers have limited energy.
