12 1234406 said that I violated the rules in Shunde, Guangdong. What is the reason why I haven't been there?

Don't believe it, don't call back, this is a fraudulent phone call. Even if there is any violation, you can go to dmv where the vehicle is located for inspection and handling during the annual review.

Violation of regulations usually refers to traffic violations, which are now called traffic violations, that is, motor vehicles, non-motor vehicle drivers or pedestrians violate road traffic safety regulations.
