Good future, K 12 is the first in the field. The teacher has nothing to say. I believe no one can hack him. We have always taken learning and thinking as the industry benchmark. Gao Shentu is more knowledgeable and thoughtful? Gaotu belongs to the lower-middle level in the training industry. Compared with many small and beautiful institutions, he is far from being mixed and shoddy. My students have taken high school courses, and they are very reluctant to be tutors. It's embarrassing for students to feel that the teacher is unprofessional.
