Online course sales belong to the business scope of courseware sales in education and training. For large companies, when applying for a license, online course sales need to be written in the business scope, and then audited by the industrial and commercial bureau. If an individual sells online courses, he doesn't need a license, and naturally there is no business scope. This is mainly because individuals want to sell their own courses in addition to distribution, and courses naturally need to be uploaded to the education platform first. These platforms themselves are equivalent to selling classes.
