The purpose and significance of teacher training are:

Establish the concept of lifelong learning and master the learning methods. "How to make education adapt to the future work when the future work changes cannot be completely predicted" is a problem to be solved in lifelong education and should also be solved in continuing education.

Learning knowledge and learning ability, knowledgeable and thoughtful: teachers are pioneers in educating students, with their own knowledge level and ability. With the progress of society, some teachers' academic ability can't keep up with the development of students. They just impart knowledge without considering the development of students' thinking. They believe that "teaching materials are our world". Now is not an era that only needs "one teacher" and "the world is our textbook", but an era that needs "a good teacher". A teacher must update his professional ability.
