1. The price is cheap.
2. Save time and effort.
3. It is more convenient to retain knowledge and materials.
4. Poor interaction (lack of children's social environment, only mother-child interaction, no offline multi-person multi-peer interaction).
5. Lack of large-scale sports equipment training (online early education teaching AIDS are generally small, lacking large-scale sports equipment that can exercise children's strength, balance, coordination and endurance).
6. There is no classroom atmosphere (offline institutions have professional teachers to take children to class together in the classroom, and the environment and education leaders are different).
