First of all, online education is the product of unbalanced development of educational resources. Especially for the small cities in 1970s and 1980s, the school has no more advanced educational ideas and high-quality resources. Online education is a way to narrow this gap.

Compared with offline education, online education has its own unique advantages. Here I want to prove three points.

First, the space advantage, parents can let their children study directly at home, reducing the cost of learning, which can be said to be "learning all over the world without leaving home."

Second, the advantage of time, on the one hand, you can plan your study according to your own time, and at the same time, you can watch online learning resources repeatedly, which is convenient for reviewing old things and learning new things.

3. Let children learn to be personalized, have more freedom to arrange their own learning content and progress, and experience the new teaching mode of VR/AR, and the learning efficiency will be greatly improved.
