Online education has low cost and wide coverage of students. The main energy can be put on website operation and curriculum improvement, and even some schools without production ability may copy other courses and tell them again as tutorials.

Low cost knowledge acquisition

Knowledge can be acquired at a lower cost. In the past, you had to take courses at Peking University (for example), but now you can hear them online, and the learning cost has become lower.

Wide coverage of students

Online education has low cost and wide coverage of students.

A leap in the education industry
