explanation: according to the Copyright Law of the People's Republic of China, anyone who copies, distributes, rents, exhibits, shows, broadcasts, disseminates, adapts or translates other people's works without the permission of the copyright owner constitutes an infringement. If the design of the cartoon cup set you bought on Taobao is someone else's original work without the permission of the copyright owner, then this cartoon cup set is infringing.
solution: if you find that the cartoon cup set you bought is an infringing product, you can complain to Taobao customer service and apply for a refund. At the same time, you can also protect your rights and interests through legal channels, and make complaints or bring lawsuits to relevant departments.
expansion note: when buying online products, we should try our best to choose formal channels to avoid buying infringing products. At the same time, we should also pay attention to copyright protection for our original works to avoid their works being infringed and stolen.
