The epidemic situation has catalyzed the development of online education. Although the development of online education is not as mature as that of offline education, it has met the needs of many people and I believe it will continue to develop in the future. The advantage of online education is that students can study anytime, anywhere, without the restriction of offline curriculum arrangement, and their learning autonomy is very strong; Secondly, at present, online education mainly teaches students personalized course content in the form of live broadcast and recorded broadcast classes, which meets the fragmented learning needs of users in the era of mobile internet and makes up for the imbalance of educational resources in traditional education. Although online education has many advantages, there are still some shortcomings, such as the inability to evaluate students' learning situation and learning effect, and the interaction with students is not as good as offline education.

But in fact, whether online education or offline education, the essence is to dispel doubts through preaching and teaching, and it is necessary to provide high-quality course content so that students can achieve something. Only traditional education has developed for thousands of years, and online education still has a long way to go.
