"Children's English has explored a relatively mature online development model, and their thinking ability can be used for reference. Moreover, users' acceptance of online education products is increasing day by day. It is relatively easy to start the market for education, and there are more talents who know the operation and management of online education.

The cultivation of online thinking ability is likely to accelerate faster than the development of online children's English. "
