Do front and rear bumper modifications require registration?

[VanJasper]

Vehicle modifications may be inspected by traffic police before implementation and require registration. Color changes constitute alterations to the vehicle's appearance, and the owner must apply for modification registration with the local vehicle management office at the place of registration. Additional Information: Illegal Modifications: Any changes beyond this, including altering the vehicle's brand, model, engine type, or modifying the registered appearance and technical specifications of the vehicle, are considered illegal modifications. Modification Activities: Any unauthorized modifications to the vehicle's chassis, engine, suspension, body color, or exterior structure without permission from the public security traffic management department, as well as any discrepancies between the vehicle's technical data and the data announced by the State Council's vehicle product authority, are classified as modification activities.
