Is it illegal to sell video tutorials on Taobao?

This kind of behavior is illegal. If the circumstances are serious, it may even be a crime.

Of course, if the cost exceeds that of 700 yuan, it is not a crime. However, the other party can ask you to stop the infringement and make a claim for your infringement.

And the compensation is not calculated according to your profit, but according to the loss caused by your behavior. For example, if you sell a discount of 1% here, you will lose 90% of your income for online schools. While charging you more than 700 yuan, you should also compensate the other party for their losses.

Of course, this is an example, and it may not be implemented as such. After all, the court has to consider the plot.

So advise the landlord to keep a low profile. . . If something really happens, you'd better ask a lawyer for legal help.
