Car soundproofing cotton is indeed effective, as I have personally experienced. After installation, the interior noise is significantly reduced, especially wind and tire noise at high speeds, making the ride much quieter and more comfortable. The principle is actually simple: soundproofing cotton can absorb sound waves and block vibrations. Applying suitable materials to areas like the hood, door panels, and floor can effectively reduce noise. There are various types of materials, with foam cotton or aluminum foil composite products working well, costing just a few hundred yuan, and you can DIY the installation. The key during installation is to clean the surface thoroughly and press firmly, otherwise, the effect will be diminished. Of course, the effectiveness varies by car model, with older cars that have poor factory soundproofing showing more noticeable improvements. Overall, it significantly enhances comfort and is worth trying, especially for long-distance driving.

Where is the license plate 'Gang A' from?

Currently, there is no license plate with 'Gang A'. Vehicles from Hong Kong entering mainland China are registered with Hong Kong local license plates (front plate with white background and black characters, rear plate with yellow background and black characters) and a black background with white characters and white border license plate issued by the Guangdong Provincial Public Security Department Vehicle Management Office, marked as 'Yue Zxxx Gang'. The first Chinese character on the license plate represents the province or municipality directly under the central government, and the letter following the first Chinese character represents the city or district. From the first Chinese character and the subsequent letter, you can determine where the vehicle belongs. A license plate is mandatory for every car to legally drive on the road. After purchasing a new or used car, the first thing to do is to register the plate at the vehicle management office; otherwise, the car cannot be driven on the road.
