The first is low cost. Among the costs of offline educational institutions, fixed investment such as venue leasing and decoration will account for 30%, which may be higher in first-tier cities such as Beijing, Guangzhou and Shenzhen. Online education takes the network as the carrier, which can transmit educational resources through the network and save the site cost. If you use a professional third-party platform, you don't need to buy software and hardware, which reduces the cost of research and development and enrollment.
Secondly, there are various teaching forms. With the development of online education, the teaching forms are becoming more and more diversified. Graphics, audio and video courses are convenient for students to learn and consolidate specific knowledge. Live teaching is more timely, and students can watch it repeatedly after class; Interactive live broadcast solves the pain point of lack of "ritual sense" in online education. Multi-person online video call restores the traditional classroom teaching, and real-time interaction with zero delay can be realized through the third-party platform.

The most important thing is that there are few steps and it is easy to get started. Many teachers with zero live teaching experience can also get started quickly.
