Why are postal cars all green?

The special colors of postal courses all over the world are determined according to their own traditions and habits. For example, Britain uses red and America uses gray. Our emissaries wear green clothes; The postal cars running on the street are also green; Even Xin's bike is green. However, in ancient China, postal signs were mainly red. According to "The Biography of Bingji in the Han Dynasty" and "The History of the Imperial Husband in the Later Han Dynasty", in the Han Dynasty, the postman wore a red headscarf, red sleeves and red and white envelopes. The purpose is to let passers-by see the postman flying horse far away so as to make way quickly. By 1905, the Frenchman Boli, who was appointed as the director of the General Post Office, proposed that yellow-green postal special color should be used in postal affairs, with green as the main primary color. This provision has been used since the late Qing Dynasty.
