What is the existence of the watchtower signal in The Twelve Hours of Chang an in history?

The watchtower signaling is real, and it can be said that there are some prototypes in history, but it is certainly not what is depicted on television. The watchtower signal can be said to be a beacon in my heart. Anyone who has been to the Great Wall and some historical cities will know it.

In these famous cities, they will have some beacons. The main function of the beacon is the same as that of the watchtower, both of which are used to transmit information. So as to achieve the purpose of defending or arresting some people.

After going to the Great Wall, you will find that there is a beacon tower not far from them, which is used to defend against enemy attacks. And if you have been to Xi'an, or Datong, you will find that their city walls will also have something like a watchtower. This thing can be said to be the prototype of the watchtower in the twelve hours of Chang'an.

In television, the watchtower's message can be conveyed through flags or shouts.

And if it's on the Great Wall, they convey it through wolf smoke, and if it's on the tower in the famous city, they will also convey the message according to the shouts and some flags, but I think TV has made some changes, because in the TV we can see that the watchtowers they convey are in many places, and in real life, when we go to the city wall, we will find that there will be some watchtowers only on the city wall. There is no one in the city, so I think there is a certain change in television.

However, it is also possible that such watchtowers also existed in ancient times. Because ancient and modern times are not the same. In ancient times, their information exchange was particularly slow, and they relied on a certain amount of manpower to transmit information.

And the speed of information transmission also determines the decisive condition for whether the war can be won. Therefore, it is possible that this thing did gradually disappear in ancient times with the change and modernization of cities.

There's no way to verify this.,It doesn't feel like something that can be known.,There must have been its own way of transmitting information in history.,But I don't know if the watchtower signaling exists.。

This should be created by the screenwriter himself, and the Tang Dynasty is expected to build this thing, but it can't have the same complex long-range communication means as in the TV series, and can only be used to watch the enemy and warn of the enemy.

For the sake of film and television effects, TV series will naturally have some fictional things, so don't believe everything in TV dramas, and of course don't believe nothing.

Most of today's TV dramas are filled with wild history, and many things are different from the real appearance of history, so I can't believe that TV dramas are staged!

How is it possible, the watchtower signal in the twelve hours of Chang'an was made up in the later period. At most, it is integrated into the TV based on some historical facts plus some ideas from the present.

Don't be stupid, a lot of things in the TV series are distorted history, and many of them are made up nonsense, and there is no historical basis at all.

I don't think the letter of forgetting the building does not exist in history, it may just be made up in this **.

I don't know in real history, but many historical dramas have performances, and it stands to reason that they exist.

This one definitely exists, and it needs to be signaled! Like the beacon tower of the Great Wall, but with a different name. It is mainly used to quickly convey enemy information.

There is no way to prove this, because it may be difficult to preserve it, and it may have been lost long ago.

Information transfer stations, watchtowers, arrow towers.

It can be said that this drama has made more people have a better understanding of the culture of the Tang Dynasty, and they are also full of interest in the culture of the Tang Dynasty.

Why is it said to be a transit station for information, in the plot, the first time to show the watchtower is the first episode, many people have the deepest impression of the watchtower here, because Li Bi said to Zhang Xiaojing that as long as he is still in Chang'an City, he can grasp any position of Zhang Xiaojing at any time, Zhang Xiaojing can't escape his control, relying on this watchtower, delivering a message every three hundred meters, so as long as it is still in the city, of course, you can monitor any target you want to monitor, and you can quickly transmit information.

Needless to say, the watchtower is located at the top of the street, and everything within its jurisdiction can be seen at a glance, and the observation distance is exactly the distance between each watchtower, so that not only all-round coverage, but also can clearly see any clues, but also to a farther distance, so the watchtower also has the role of a lookout, as the eyes of Jing'an.

The arrow tower is the offensive role of the watchtower, in the first episode, Li Bi introduced the watchtower to Zhang Xiaojing, talking about its defensive role, there is a watchtower every three hundred meters, each watchtower is covered with marksmen, you can accurately aim and shoot the objects within your own range, so the watchtower is also an arrow tower in Chang'an City, as a preparation for defense, after all, there is an arrow tower every three hundred meters, and anyone who resists can't stand it.

The signal tower, which is used to transmit signals, is similar to the bonfire to transmit information, and if there is any special situation, the signal will be released in time, so that the sudden information in each area can be known in time, and the Jing'an Division can better grasp the intelligence.

The information transmission intermediary will pass on to the next place according to the information given by each watchtower, until the news is delivered to Li Bi's hands, and the role of the watchtower is still very important in this drama, and you can know the development of things in time.

The watchtower in Chang'an at 12 o'clock is a kind of tower used to transmit news, and as long as it is still in Chang'an City, it will definitely be monitored by the watchtower, for example, it is equivalent to a watchtower.

In ancient times, the watchtower was used as a sentry post for observing the enemy in ancient wars. The role of the watchtower in "The Twelve Hours of Chang'an" is also similar, which is used to transmit information to Jing'an Division, and then there is a special person to tell Li Bi the news transmitted by the watchtower.

I think the watchtower should be able to better monitor the situation in Chang'an City, prevent bad incidents such as fights and brawls, and if there is an enemy infiltrating Chang'an, it can also be reported in time.

In "The Twelve Hours of Chang'an", many watchtowers on the street are used to transmit information, a bit like today's cameras, all-round artificial monitoring, ancient times do not have to be modern high-rise buildings, watchtowers are very important.

On the surface, it is to see the scenery from above, but in fact, it is possible to communicate with each other. And the way of communication is very special. It can prevent outsiders from being able to hear

It's quite like a modern camera, which is responsible for monitoring Chang'an City, and then transmitting information through a code, the role of a signal tower.

Yes, this watchtower is nothing more than a place to see the scenery, just like some real estate, standing on a high place is to see the scenery, and at the same time you can have a good chat with some people or say some secret things.

Similar to our current radar and sending and receiving signals, in Chang'an at that time, if you want to find a person or observe a thing, you can transmit it to Jing'an Division in a short time, which can be regarded as the earliest newsletter.

In "The Twelve Hours of Chang'an", I think the watchtower message exists, but it's not so magical.

The watchtower message is real. It's just that his role is exaggerated even more in the play.

The watchtower really existed, but it was not as exaggerated and magical as it was said in the play, it was a watchtower, which could only observe things around and from afar, but could not communicate.

It should be real, but it's hard to say how many functions there are, and it's a bit exaggerated in the TV series.

It should exist, the building is the same, but the name should be different.

I think there should be no such building in ancient times, and it was not a flying pigeon in ancient times, and this method of transmission is of little significance.

Historically, of course, it existed, but it wasn't so magical.

In ancient times, there was this kind of messenger building, but I don't understand the mysteries of it!

Sing a song with you, please listen to it for me.

First date, first time watching a movie.

In our Datang, the main common ways of communication are: post station, flying pigeon book, beacon fire, flag language, etc. Each method of communication has its own best suitability, and after all things considered, we chose the way of flag language and drumming.

Flag-speaking devices are set up on all four sides of each watchtower. Flag devices are usually three-by-three or two-by-nine wooden lattices. Each grid can be placed in white and purple colored cloth.

The obvious color difference is enough for the watchtowers, which are spaced at a distance of 300 paces, to read each other's information in time. Place the lights in the lattice and display them with light instead of bunting. Although there were no curfews in the days when Chang'an City was brightly lit at night, there was no one at this height who could compare with the bright light of the watchtower.

In addition to visual transmission, we also have the watchtower with sound to convey information. In order to make the drum sound easily distinguishable in the noisy city of Chang'an, we specially imported lizard skin drums from Persia. The sound of the lizard's skin drum is very distinctive, low and clear, and it travels a long distance, so it will never be confused with the sound of the festival drum, street drum, and dungwen drum.

In this way, whether it is the Wuhou who is on standby, or the brigade army who is handling cases outside, once the drum of the watchtower sounds, they can also respond immediately, which greatly improves our work efficiency.

Now that the issue with the sending device has been solved, the next thing I need to think about is information encryption. As a highly secure Jing'an Division, the transmission of information must be encrypted, which is my mandatory requirement. So I gave Xu Bin the task of configuring a reasonable encryption language.

In addition, people who are not specific to Jing'an Division will never be able to read the meaning of the information we disseminate, so as to ensure the security of our information.

The watchtower shown in "The Twelve Hours of Chang'an" can indeed convey information. In fact, in the first episode, the hero explained the role of the watchtower: it can not only monitor the situation in Chang'an City, but also use the whiteboard on the wall to transmit secret information without being known by outsiders.

But in fact, there is no such watchtower in the Tang Dynasty in history, there is only a post set called "watchtower", which plays the same role as a monitor, but it cannot transmit information.

To say that the ancient passwords of our country can be traced back to the Western Zhou Dynasty at the earliest. Legend has it that Jiang Ziya invented the "Yin Fu" and "Yin Book":Yin Fu is a kind of Jane or Piece of Bamboo with different sizes and lengths, and different sizes of Jane represent different meanings, a total of eight kinds.

But these eight simple symbols are far from enough to convey complex military information, so there is a "Yin Book". Yin Shu is to divide the complete document among three people to carry, so that even if one person is caught, the secret will not be revealed.

Of course, this cryptographic system is not perfect. So in the Song Dynasty, the military strategist Zeng Moliang invented a cryptographic system. He numbered the phrases commonly used on the battlefield separately and used another unrepeated five-character poem as a tool for decoding.

When a general leads an army into battle, the chief general will hand them a codebook and improvise a poem as a tool for decoding. In this way, as long as the lord sees the "words" in the poem contained in the document sent by his superiors, he can translate the corresponding meaning in the code book.

Compared with the ciphers of the Zhou Dynasty, the way of transmitting ciphers in the Song Dynasty has been much more advanced, and the reliability has also increased a lot, which can be said to be the prototype of modern ciphers.

Special signals.

The watchtower of "The Twelve Hours of Chang'an", as the ears and eyes of Jing'an Division, how did it transmit messages to Jing'an Division in silence, and it was able to be accurate in many cases, and it could not be known by other people The information inside, what kind of ability did it rely on? In fact, it still relies on a password like modern to transmit information, of course, this password is only known to one's own people, and outsiders are not aware of it.

In the first episode, we can clearly see how the watchtower transmits the message, when the Jing'an Division issued an order, according to the first instruction, the watchtower turned into a watchtower at this time, looking for the instructions issued by the headquarters, looking for the people who need to be found, and setting up a watchtower every three hundred meters, which is used as a message transmission center, when the headquarters issued an instruction, the watchtower closest to the headquarters will send out a signal, that is, the shouting that we saw for the first time.

After the first watchtower shouts, the back of the watchtower is a white cloth of the nine-square grid, which is lined with blue cloth from the inside, when the number appears, someone will operate behind it, and the number will be changed out, that is, according to the position of the number, the white cloth on the nine-square grid is taken away, revealing the blue cloth, and the next watchtower sees the signal of the change of the white cloth of the first information transmission point, and will adjust the white cloth behind it according to the content, so that the next watchtower can see this information.

Therefore, the watchtowers are relying on such operations, passing layer by layer, and passing the most original information back to the headquarters for decoding, many people feel very strange, why pass a number, you can only password, you can know the meaning inside, this is the decoding that needs to be reached, Jing'an Division has its own password system, the digital information obtained by the front party is back to the headquarters, and there will be a separate person at the headquarters to decode the number, which is also the decoding of the digital password often seen in spy war movies.
