First of all, I think the main reason for low-level mistakes in online classroom teaching is the problem of video tutor. Online classes are generally recorded in advance, and problems should be found in later editing. Mistakes can only show that you are not careful and responsible when making videos, so this requires those producers and disseminators of online videos to treat them with a more rigorous attitude. Secondly, these educational institutions related to online education should also be strict with themselves. In addition, China can also introduce relevant laws and regulations to strictly regulate the online education industry.
