How fast is the 800 mile expedited used to transmit military intelligence in ancient times?

Ancient times were not as developed as we are in modern times, and it was convenient and fast to transmit information or documents. In ancient times, the exchange of information between people was achieved through some relatively backward methods, such as flying pigeons and passing books.

In the military, there is a more commonly used beacon fire, and there is a post system that requires a lot of manpower and material resources to be formed.

The ancient post system has undergone a process from its inception to its development to a relatively complete and mature one. Most of the information passed between the different stations was important official documents or important and urgent military information. Therefore, this system is very important to the imperial court, because many important news need to be conveyed by it.

At that time, in order to make the transmission of information faster and more timely, the post station would be equipped with fast horses, and there was a very urgent situation, and the speed of sending letters could reach 800 miles a day, which is probably even a modern means of transportation.

are not easy to reach.

Under normal circumstances, these documents or important military information are not particularly urgent, so it is enough to use an ordinary fast horse to deliver the letter. However, in some very special circumstances, such as an emergency at the border or someone attempting to rebel, the 100,000 urgent news must be expedited at a speed of 800 miles. Generally speaking, the distance between each post station was about twenty miles, and the messenger had to change to a fast horse to continue his journey at each place, and these horses could travel thousands of miles a day if they ran as hard as they could, but it was very physically demanding.

At the same time, it is also very hard work for the messenger, because he has to be in a hurry all the time, he simply does not have time to stop to drink or eat, and to achieve such a fast word, it is very physical for the sender.

There are also very high requirements. So we will see in the TV series that in an emergency, the messenger is often exhausted and collapsed after arriving at the destination.

The legendary 800-mile rush is rarely used, but it is needed in some particularly urgent situations. Therefore, in ancient China, the construction of the post system was still very important, and the imperial court would spend a lot of money every year to build and improve this aspect, but also to convey information more smoothly and quickly.

The speed is about 30 miles per hour. Traveling 800 miles a day, 24 hours a day, which is converted into 33 miles per hour, which is about the same speed as a battery car.

The 800-mile expedited is to spend one day to achieve the effect of 800 miles of expedited under the condition of not caring about running dead horses, not caring about killing people along the way, and not caring about the physical strength of horseriders.

In ancient times, horses were used to transmit letters, and urgent documents could not be stopped for a moment, which could break several horses and tire many people to death, because they were all about war and could not relax.

The 800-mile expedited will take two days at the earliest.

In ancient times, the file transmission relied on the post station, generally every 20 miles there was a post station, once the official document that needed to be transmitted was marked with the words "immediately fly", according to the provisions of the requirements of 300 miles per day, in case of emergency, 400 miles per day, 600 miles, the fastest up to 800 miles. When delivering urgent documents, each post station uses fast horses, so that although it is not a thousand miles horse, every horse runs to the death. "600 miles expedited, 800 miles expedited" is used to indicate the urgency of the situation.

In literature, there is a wonderful description of this: "Eight hundred miles in an emergency!" Eight hundred miles expedited!

A roll of yellow dust rolled, and the horse galloped in, but when he saw the figure flickering, he jumped and dismounted. Shouted "Eight hundred miles urgent!" The gold medal is given, the obstructor dies, and the rebel dies!

Then I saw the smoke and dust billowing out, and the rider had already left! At this time, the ancient road is cloudy, and the sky is clear!

The Tang Dynasty poet Cen Shen wrote in the poem "The Judge of the Character on the Way to Longshan at the First Passage" that "a post passes by a post, and the post ride is like a star stream; Pingming sent Xianyang, curtain and Longshantou". Here he compares the stagecoach to a shooting star. According to the official regulations of the Tang Dynasty, fast horses are required to travel about 180 miles a day, and faster ones require 300 miles a day.

The fastest requirement is 500 miles a day. On November 9, Tianbao 14, An Lushan rebelled in Fanyang. At that time, Tang Xuanzong was in Huaqing Palace, and the two places were separated by 3,000 miles, and Tang Xuanzong knew the news within 6 days, and the transmission speed reached 500 miles per day.

It seems that the most urgent communication in the Tang Dynasty required a daily journey of 500 miles.

In the Tang Dynasty, one foot was combined into a meter, and one mile was combined with a meter, and from the current point of view, eight hundred miles could not be faster, and it would take two days.

Very urgent. It can be said that it is a fast horse, and if you can't stop and rest on the road, you will also tire many horses to death, which is equivalent to the speed of driving now.

The ancient 800 li rush is just a saying, after all, the fastest speed in ancient times was horseback riding, so the speed of horseback riding is comparable to that now.

It is a state of great urgency, and the 800 li rush is only used when there is a war, or when the general sends documents to the emperor. Equivalent to the speed of a car now.

1. The explanation of the ancient 800 miles expedited: there is an express station every 20 miles, just like our current express point, which was called a post station in ancient times. And each post station will store the fastest horses, will also prepare sufficient supplies, when transporting news, each post station, will quickly change people and horses, so that the fastest speed, the information can be transmitted.

If nothing else, then the distance of 800 miles, it will only take about a day or so to get the news to the emperor, and if it is a little faster, it can be delivered to the Yellow Emperor on the same day.

2. And our express delivery today is also very convenient, no matter how far away, it can generally arrive in two days and three days. We call it express today, and in ancient times it was called a post station, and the location of the First World War is also particular, he is not like our express today, choose a place with a lot of people, the post station will generally be selected in a remote place, and there is a special route, so that the information is transmitted in a more timely manner.

We know from ancient TV dramas that when an important military event or an order is transmitted, 800 miles is urgently dispatched. 800 km is the fastest way to deliver messages, what is the concept of 800 km? How come no one is in the way?

First of all, we all understand that in the past, transportation was not very good, and now, the most important thing is to use horse-drawn carriages. The ancient method of 800 li is equal to more than 400 li today. After a long-distance run, the war horse also has to rest.

After all, horses are not machines, and they cannot run hundreds of miles in one sitting. As a result, there were many inns in each dynasty. The inn was a place for officials to deliver letters, eat, board ships, and change horses.

This shows how important this post house is.

Take the Tang Dynasty, for example. The post houses of the Tang Dynasty were distributed in the country and were divided into three categories: Yilu, Shuiyi and Shuiyi.

Usually 20 to 30 kilometers apart. In this country, there are more than 1,600 post offices with 20,000 employees. He is a member of the army.

The management of post roads in the Tang Dynasty was very strict. There must be no errors when sending the email. If the fault was severely punished, the Tang dynasty would prolong the letter.

Eight hundred miles, 300 kilometers a day, if it is at a critical juncture, you can drive 400 kilometers, 500 kilometers, 600 kilometers a day, and the maximum speed can be 800 kilometers per hour. In the fourteenth year of Tianbao, An Lushan rebelled in Fanyang County, and the distance between the two sides was about 3,000 kilometers. However, within six days, the news of the An Lushan rebellion spread in Beijing, more than 500 kilometers a day, and the speed of its spread can be imagined.

Judging from the length measured by the past dynasties, the length of the Tang Dynasty was about 531,500 li is kilometers, and 800 li is kilometers, which is very amazing. Eight hundred miles is a very urgent state affair, and there is no economic **, so the court is very concerned about it. If it is attacked halfway, the government will inevitably send a large army to kill it, or even destroy the entire army, so no one dares to rob it.

As the name suggests, "800 miles expedited" means that a horse has to run 800 miles a day. In our modern times, it takes 8-10 hours to achieve this if it is a car, and 2-3 hours if it is an airplane. If it is express delivery, it usually takes 3 days from the order to the delivery, 800 miles.

800 miles expedited means that every time you arrive at a post station, you will change people and horses, but this letter will always be delivered to the place as quickly as possible, which is equivalent to our fastest speed now, even faster than playing **.

In ancient times, it was often 800 li expedited when transmitting war reports, which was quite fast, and it would be delivered within a day of 800 li. This is the way to deliver the tightest possible message.
