This study divided video content of current representative YouTube channels on Chinese language education into internal and external elements for analysis. By examining these channels, this study found that they have various external and internal elements. In addition, YouTube classes also have certain distinct characteristics that are non-existent in traditional classroom or face-to-face classes, and show potential to serve as a new educational medium that can fill the gaps in existing classroom classes.
