Chunghwa Post
The Customs Post Office of the Qing Empire was established in 1878 by Robert Hart at the suggestion of the foreign powers, with branch offices in five major trading cities. On 20 March 1896, the Customs Post Office became the Great Qing Post, which in 1911 became independent of the customs service. The Great Qing Post became the Chunghwa Post in 1912. Chunghwa postal service had signed a contract with the China Airways Federal group in 1929 to transport airmail on the Shanghai-Hankow, Nanjing-Beijing, and Hankow-Guangzhou routes. Chunghwa Post had functioned as the main postal service provider of Mainland China until 1949.
