The Revolutionary Army's uprising at Wuchang on October 10, 1911, soon jointed by other provinces that finally overthrew the Manchurian government. Revolutionists led by Dr. Sun Yat-Sen founded the Republic of China on January 1, 1912. Ching Dynasty formally ended with the abdication of Emperor Hsuan Tung (Pu Yi) on February 12, 1912. The Chinese Imperial Postal Service became Chinese Republic Postal Service and Post of China entered a new era.

Despite of the difficulties and problems under circumstances of late Ching Dynasty, the Chinese Imperial Postal Service made remarkable achievements in her 15 years history. The number of post office/branch grew from 24 in 1897 to 6,250 in 1911. The postal route extended 190,000km long and reached to all provinces. The CIP also signed postal agreements with several countries' postal authorities for exchanging mailbags and recognition of Chinese postage stamps, and laid foundation for China eventually becoming a member of UPU. Thanks to the joint efforts of foreign and Chinese postal staffs, the Postal Service turned out to be one of the most productive sectors at that time. As for philatelist, many of the rarest gems of all Chinese philately were from this period as well as the most colorful postal history treasures.
