1. The online education system can accommodate hundreds or even thousands or even hundreds of thousands of people, which fully enlarges the resources of famous teachers and reduces the per capita expenditure of students.

2. The price offline is more than three times that online. Under the same effect, why don't users choose cheaper ones?

3. With the impact of the Internet, pure offline education has also become difficult: the loss of good teachers and the confusion of the market.

Second, the extracurricular cost is small.

1. In the traditional face-to-face teaching environment, students and teachers need to attend classes for two hours at the designated place, and students and teachers need to pay at least one extra hour on the road.

2. On-line, avoid the pain of bumping back and forth, save time and have superior efficiency.

3. Multi-terminal online learning: the expansion of computer PC, mobile phone and WeChat is inevitable. As long as there is a network, you can listen to lectures or even download them online anytime and anywhere, which has become the first choice for many mobile phone controllers.

4. The construction of network platform will become the same daily service as tap water, thus realizing the impact and subversion of traditional education and training.
