Not the same teacher. In order to make up for the shortage of famous teachers' resources, Zhibo Education creatively put forward the dual-teacher teaching mode in the field of upgrading from college to undergraduate. All subjects are equipped with teaching assistants, and students can get professional and comprehensive learning guidance in class and after class through the way of teaching by teachers and answering questions by teaching assistants. Online students are also equipped with full-time online teaching AIDS, whose functions are different from those of offline teaching AIDS, so as to adapt to the characteristics and needs of online learning to the greatest extent. Therefore, Zhibo's online and offline teacher is not a teacher.
