To put it simply, after all, I have been engaged in this line for several years. Up to now, there have been various forms such as 1-to-1, small class, online live broadcast, online recording and broadcasting, and dual-qualified teachers, and even gamification derived for their own liking, but none of them can guarantee the effect. They just recruit students with gimmicks, marketing strategies and users' anxiety, so the education industry has never appeared like Ali and Tencent, even Didi. In my opinion, pens, papers, books and courses have always been with students since ancient times, and their study habits are deeply imprinted in their minds. Therefore, the current education methods either repeat the school model and cannot solve the problem of personalized counseling, or do not conform to the students' study habits and scenes. Occasionally, there are patterns that can solve personalized problems and conform to the learning scenes, but they cannot be batch-printed, such as 1 to 1, which is a minority after all.
