Craftsmanship means that some people claim to be experts or masters in a certain field and carry out publicity and sales activities in this name. Whether these people's behavior constitutes fraud needs to be judged according to specific circumstances. If their behavior involves false propaganda, fraud and infringement of consumers' rights and interests, it may constitute fraud.
Therefore, if you encounter this kind of behavior, it is recommended to choose carefully and pay attention to protecting your rights and interests. If you think that your rights and interests have been infringed, you can complain and report to the relevant departments.
