1    Introduction
1.1    Purpose and significance
    Vehicle license plate is equivalent to a vehicle's identity card, as well as the only certificate of a vehicle's identity in public places. For this, China's traffic management department has paid much attention to the management of vehicle license plates and has developed a set of strict management regulations. Among them, the production, installation and maintenance of vehicle license plates are subject to the unified management of the policy-making departments. 本文来源:http://www.mamitama.com/a/www.malifuke120.com/
