The function of beacons is to warn people, so what should be used to send messages when the weather is bad?
When the weather is bad, messages can also be conveyed by means of flags, drumming, lights, flying pigeons, etc.
The main way of transmitting information in ancient times was beacon fire. Do you still remember the story of last week in history, when King You smiled to win a beauty, and the beacon fire played on the princes? The method used at that time was to use beacons to convey messages, which was also the most effective way to convey military information in ancient times.
In ancient times, there was no electricity, and there were not as many lighting facilities as there are at night, so it was very dark at night, and fire was easy to spot. This method is not feasible in modern times. After all, the light is too bright and it is not obvious where the fire started. Therefore, the beacon reporting method was gradually eliminated.
In ancient times, there was also a way for soldiers to rush to report the news, which could also resist the influence of bad weather. In ancient times, there were post stations. When you arrived at the inn, you could change horses and people, passing messages like a baton. In ancient times, some fresh fruits were transported to the palace in this way.
In addition, flying pigeons can also be used to pass messages. However, there is a possibility that the letter passed by the flying pigeon may be intercepted midway, or the pigeon may die unexpectedly, so it is not very safe. After all, homing pigeons also need training. Being able to remember the route does not necessarily mean they have good psychological quality. If the pigeon is timid, it may be frightened by war and change its original flight route.
If it is daytime, you can also use semaphores. Because the soldiers stationed at the Great Wall in ancient times were usually relatively close and could see each other. If there is a specific semaphore, the message can be conveyed by waving the flag. There is also a precedent for waving flags to command troops on ancient battlefields, so it should not be difficult to convey information by waving flags.
In addition, there are ways to transmit information through lights. After all, the Kongming Lantern invented by Zhuge Liang is similar to the beacon. They all borrowed from the ancient dark environment to convey information through fireworks and lights.
