What color is the post box

Countries around the world choose different colors for their postal symbols, with the United States using gray, the United Kingdom using red, and France using yellow ...... After the founding of New China, at the first national postal conference, it was decided to use green as a special symbol for the postal service.

Green symbolizes peace, youth, lushness and prosperity. As a result of this regulation, China adopted green color for post boxes, postmen's clothes as well as postal packages and postal vehicles.
