What do TM and R in trademark symbols mean respectively?

The TM symbol of a trademark refers to the symbol that you can put on after you register a trademark and receive a letter of acceptance for trademark registration, indicating that you have the priority to use the trademark, or reminding others that the trademark has been submitted for registration by you, so that others can stop thinking about cybersquatting. R means that the trademark has been registered successfully, and you are the legal owner of this trademark. If someone else uses this trademark, it is an infringement on you. You can order them not to use this trademark again according to the legal provisions.
