The story of the ancients transmitting information.

China is one of the first countries in the world to establish an organized information transmission system. As early as 3000 years ago, there were records of information transmission in Shang Dynasty.

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 of a small stamp by the First Congress of the All-China Philatelic Federation 1982, which shows that Jiayuguan is one of the cradles of information culture in China.

A whole set of evacuation system was formed in Qin and Han Dynasties. Especially in the Han Dynasty, the documents delivered were graded, and the documents of different grades should be delivered by special personnel and special horses in accordance with the prescribed order and time. Sending and receiving these documents must be registered and marked with time to show responsibility.

During the Sui and Tang Dynasties, the cause of evacuation developed unprecedentedly. The official postal transport line in the Tang Dynasty centered on Chang 'an, the capital city, radiating in all directions and reaching the frontier, with a post station about 30 miles away. According to the Six Codes of the Great Tang Dynasty, at its peak, there were 1 639 post stations in China, with more than 20,000 people specializing in postal services, including 1.7 million post soldiers. The post is divided into three types: land post, water post and waterway merger. Each station is equipped with a station house, a post horse, a post donkey, a post boat and a post yard.

In the Tang Dynasty, there were also explicit provisions on the itinerary of the post station. Lu Yi's trotters walk six posts a day, that is, 180 Li, and then there are about 300 Aliri, and the fastest requirement is 500 Aliri. Pedestrians travel 50 miles a day; Sailing against the current, the river is forty miles, the river is fifty miles, and the other six miles; When it is good, specify 100 to 150 miles. The poet Cen Can wrote in the poem "A Judge on the Road to Longshan" that "after a post, the post rides like a Milky Way; Pingming sent Xianyang, the curtain and the top of the mountain. " Here, he compares the post horse to a meteor. On November 9th, 14th year of Tianbao, An Lushan rebelled in Fanyang. At that time, Emperor Xuanzong of the Tang Dynasty was in Huaqing Palace, three thousand miles apart. Within six days, Emperor Xuanzong of the Tang Dynasty learned the news, and the speed of communication reached 500 miles per day. It can be seen that the organization and speed of postal communication in Tang Dynasty reached a high level.

In the Song Dynasty, all official documents and letters were called "delivery", and "express delivery shop" appeared. There is a bronze bell tied to the collar of the riding whistle in a hurry. Running on the road, ringing the bell during the day and lighting a fire at night, the person killed is not responsible. Shopping for horses, shopping for people, rain or shine, day and night. In the early years of Southern Song Dynasty, Yue Fei, an anti-gold general, was forcibly recalled to Lin 'an from the front with 12 gold medals by Song Gaozong. This kind of gold medal is a gold plate sent by express delivery, indicating urgency.

There are also bells and drums, fireworks, pigeons, semaphores, wolf smoke and other ways to convey information.

Marathon was originally a place name in Greece. In 490 BC, the Greek army repelled the invasion of the Persian army in the Marathon Plain. The messenger Fedipides ran from marathon to Athens. After reporting the news of victory, he fell to the ground and died of exhaustion.
