1) There is no big data foundation in the whole education industry. Because the teaching content and process are not standardized, the collection channels and methods are not objective enough, and the data volume is not large enough to form the basis of big data analysis;

2) A large number of high-quality educational resources have no informationization, lack of unified platform management of educational resources, difficult drainage, poor promotion and insufficient application, which is not conducive to learning and sharing; The existing information education resources are scattered and not systematic; Especially in the third-and fourth-tier cities, the demand at both ends of the supply is strong, and the demand for extracurricular tutoring for students in the third-and fourth-tier cities is strong, but the local excellent teachers are limited;

3)K 12 is still a field strictly protected by national policies, and it is also a highly monopolized market, so it is difficult to teach privately;

4) 4) The business model of K12 is oriented to parents, but the user experience is oriented to students, so it is very difficult to coordinate the two. In practice, online education is difficult to compete with traditional school education, so there are many speculative concepts;

5) Compared with K 12 stage, parents of preschool children are younger, have no pressure to go to school, have less psychological burden of using online education, and are more willing to try online education system;

6) At present, foreign countries are trying a more scientific quality education model, and I believe this concept will gradually penetrate into China; Online preschool education has unique strategic value. Although the short-term market value is not clear, it is of great significance in cultivating children's habit of using online education system and enhancing parents' confidence in online education.
