When you do home medical equipment sales, you treat yourself as a medical student doing your practice, and you are even afraid that people will know you are a salesperson. Is this against the law?

Because you are deceiving consumers with non-existent experiences, it violates the principle that sellers should abide by the principle of honesty and trust in the Consumer Protection Law. It's also illegal now. If you did not make false publicity for the product, did not exaggerate the efficacy of the product, did not cause serious consequences, as far as the false experience you told, the consequences of illegal behavior is not serious, the possibility of pursuing your responsibility is not very large.

But if it causes serious consequences, then the responsibility can be big. You have to be careful!
