Illegal.

If it is a registered trademark, it can be marked with R. There is no problem and it does not involve infringement.

General trademark registration is not compulsory! Food, medicine, tobacco and alcohol are compulsory registration categories

After the trademark is certified, it can be marked with a circle R or circled, or it can be marked with nothing

The shopping mall does not allow this. The internal regulations of the mall have nothing to do with the law. Legally, it is voluntary for registered trademarks to be marked or not.

You can mark "R" after getting the certificate. If you just get the acceptance notice, you can go to the mall and mark "TM".
