Can anyone tell me what were the characteristics of the ancient use of post errands to convey inform

As early as the Shang Dynasty more than 3,000 years ago, information transmission was recorded. Passing by horse is called a post pass, which is an early organized form of communication. Located in the square of Jiayuguan railway station, the "post envoy" sculpture, it is taken from the Jiayuguan Wei and Jin mural tombs, the post envoy holds a simple paper, the post horse is four-legged in the air, and the speed is fast.

In 1982, the First Congress of the All-China Philatelic Federation was used as a theme pattern for small stamps, which shows that Jiayuguan is one of the birthplaces of China's information culture.

During the Qin and Han dynasties, a complete set of post transmission systems was formed. Especially in the Han Dynasty, the documents transmitted were divided into grades, and the documents of different grades should be transmitted by special personnel and horses in accordance with the prescribed order and time. The sending and receiving of these documents must be registered, and the time should be indicated to clarify the responsibility.

During the Sui and Tang dynasties, the post industry developed unprecedentedly. The official postal transportation line of the Tang Dynasty took the capital Chang'an as the center, radiated to the four directions, and went directly to the border area, with a post station roughly 30 miles. According to the records of the Six Classics of the Tang Dynasty, there were 1,639 post stations in the country at its peak, with more than 20,000 people specializing in post services, including 17,000 post soldiers.

The post post is divided into three types: land post, water post and waterway merger, and each post station is equipped with a post house, equipped with a post horse, a post donkey, a post boat and a post field.

In the Tang Dynasty, there were also clear regulations on the itinerary of the post post, and the land post fast horse walked 6 posts a day, that is, 180 miles, and then 300 miles a day, and the fastest required 500 miles a day; Walkers travel 50 miles a day; When sailing against the current, the river travels 40 miles, the river travels 50 miles, and the other 60 miles; When going down the river, it is always 100 to 150 miles. The poet Cen Shen wrote in the poem "The Judge of the Character on the Way to Longshan at the First Stage" that "one post passes through one post, and the post rides like a stream of stars; Pingming sent Xianyang, curtain and Longshantou". Here he compares the stagecoach to a shooting star.

On November 9, the 14th year of Tianbao, An Lushan rebelled in Fanyang. At that time, Tang Xuanzong was in Huaqing Palace, and the two places were separated by three thousand miles, and Tang Xuanzong knew the news within 6 days, and the transmission speed reached 500 miles per day. It can be seen that the organization and speed of post communication in the Tang Dynasty have reached a very high level.

In the Song Dynasty, all official documents and letters were collectively referred to as "delivery", and "express delivery shops" appeared. There is a copper bell tied to the collar of the post horse of the express delivery, and when galloping on the road, the bell is ringed during the day, and the fire is raised at night, and the person who is killed is not responsible. Shop for horses, number of shops for people, rain or shine, day and night.

In the early years of the Southern Song Dynasty, Yue Fei, the anti-gold general, was forcibly recalled to Lin'an from the front line by Song Gaozong with twelve gold medals.

According to the legend of one post station, each post station has horses to change, and there is also some food and water for the post to eat.

In ancient times, file transmission relied on post stations, generally one post every 20 miles. Once the official document that needs to be delivered is marked with the words "immediately fly", it should be 300 miles per day according to the regulations, and in case of emergency, it can be 400 miles and 600 miles per day, and the fastest can reach 800 miles. "600 miles expedited" and "800 miles expedited" are used to indicate the urgency of the situation.

According to the regulations of the Tang Dynasty, fast horses require about 180 miles a day, faster leads require 300 miles a day, and the fastest requirements are 500 miles a day. On November 9, the 14th year of Tianbao, An Lushan rebelled in Fanyang. At that time, Tang Xuanzong was in Huaqing Palace, and the two places were separated by three thousand miles, and Tang Xuanzong knew the news within 6 days, and the transmission speed reached 500 miles per day.

According to the records of the "Six Classics of the Tang Dynasty", at its peak, there were 1,639 post stations in the country, with more than 20,000 personnel specializing in post services, including 17,000 post soldiers. The post post is divided into three types: land post, water post, and land and water merger, and each post station is equipped with a post house, equipped with a post horse, a post donkey, a post boat and a post field.

The post station is a place in ancient China for people who pass official documents and military information or for food and lodging and changing horses on the way to and from **.

The post station has existed since the pre-Qin period, and has been perfected in the Qin and Han dynasties. But it was only after the Mongols ruled China in the 13th century that the term appeared. Before the Yuan Dynasty, "post station" was only called "post", and the word "station" was a foreign word, derived from the transliteration of the Mongolian word "zhan chi" (jamuci), "zhan chi, the translated name of the post legend".

During the Yuan Dynasty, "Zhanchi", referred to as "station", was widely established throughout the country, and since then, the meaning of "station" has been integrated into the Chinese language and evolved into the two-syllable word "station".

The role of the post station: the post station has an important position and role in the ancient transportation of our country, in the case of very primitive means of communication, the post station is responsible for a variety of political, economic, cultural, military and other aspects of the information transmission task, to a certain extent is also a part of the logistics information, but also a specific network transmission and network transportation. Although the forms and names of the ancient post stations in China are different, they are closely organized, hierarchical, and complete in formalities.

The feudal monarch relied on these post stations to maintain information collection, command issuance and feedback, in order to achieve the goal of feudal rule control. Due to the limitations of the historical conditions at that time and the limited level of scientific and technological development, its speed and quantity cannot be compared with today, but in terms of its degree of organization, the coverage level of the transportation information system is no less than that of modern communication and transportation. It can be said that the achievements of that time are also part of the foundation of our modern civilization.
