Can be used, but not protected by law. Trademarks in our country implement the principle of voluntary registration, so you can just use them without registering them. Currently, a large number of trademarks in use in our country have not been registered. However, since our country's laws only protect the exclusive rights of registered trademarks, the rights foundation of unregistered trademarks is very unstable. Once those unregistered trademarks are registered by others, your brand will fall into the hands of others.

It can be used, please keep the evidence of use. Such as products, packaging, color pages, invoices, etc. Another reminder is that TM has little meaning in China, and it does not mean that the trademark is under application. It is just a statement from the user that I have used this word or graphic as a trademark and it has no legal significance. Such evidence can be used in court as evidence of prior use to prevent the other party from registering a trademark or canceling the trademark. The evidence must be conclusive and powerful, and legal procedures must be followed. It is still recommended to register a trademark, which can save a lot of trouble. At least it's more cost-effective than hiring a lawyer to litigate. The registered trademark owner can have the infringing products removed from the shelves if he complains to the Industrial and Commercial Bureau. It’s as simple as that.
