The Shanghai+letter +Y+ four-digit license plate refers to a rented car (with a car rental business license), and part of it is used for car operation.

Car rental industry is called transportation service company. Because of the advantages of no insurance, no annual inspection and maintenance, and free replacement of models, it uses car rental instead of car purchase to control the cost of enterprises. This management method, which is very popular in foreign enterprises, is gradually favored by domestic enterprises, institutions and individual users.
