The history of China Post Station;

The post station is the place where officials who passed military information boarded the bus and changed horses on the way in ancient times. The border guards transmitted information and were controlled by the ancient customs, navy and navy. During the first 12 dynasty in ancient Egypt, there were records of transmitting information.

China is one of the first countries in the world to establish an organized information transmission system. It can be traced back to Oracle Bone Inscriptions in Shang Dynasty more than 3,000 years ago. Post-horse relay is an early organized mode of communication.

The "Postman" sculpture is located in Jiayuguan Railway Station Square, based on the mural tomb of Wei and Jin Dynasties in Jiayuguan. With a simple document in his hand, the postman galloped at high speed on all fours. This brick mural was taken as the theme pattern of small stamps by the First Congress of the All-China Philatelic Federation in 1982, which shows that Jiayuguan is one of the birthplaces of information culture in China.

From the narration of books such as Chunqiu and Zuozhuan, we can know that there were three modes of communication at that time: one was "biography", which was delivered by car; The second is "mail", step by step; The third kind is "post", which is called "horse delivery". Later, due to the high cost of car delivery, it was gradually discontinued, leaving only step delivery and horse delivery, so it was renamed as "post station".
