What place does 'Qiong' represent on license plates?

[Geoffrey]

Qiong is the license plate designation for Hainan Province. Here is an introduction about license plate numbers: 1. A license plate number is an identification tag for vehicles. The significance of a license plate number to a car is like an ID number to a person—it is a unique symbol. 2. Different colors of license plates represent different types of users. White represents military or police plates; blue represents ordinary small vehicles; yellow represents ordinary large vehicles; black represents foreign investors in China or important figures. 3. Motor vehicle license plate numbers consist of a registration authority code and a plate number. For cars, the license plate number has a two-row structure: the upper row is the registration authority code, and the lower row is the plate number. For motorcycles, the license plate number has a left-right structure: the left side is the registration authority code, and the right side is the plate number.
