As early as the Zhou Dynasty, China had a method of transmitting information by bonfire. As a primitive means of acousto-optic communication, bonfire served the ancient military war. From the border to the capital and the border, a beacon tower is built at regular intervals. When the enemy invaded, firewood was stored inside, and the fire alarms were lit one by one. When the princes saw the fire, they immediately sent troops to help and resist the enemy.
During the Western Zhou Dynasty, in order to guard against enemy invasion, the "bonfire tunnel" was used as the contact signal for border defense emergency. In the ancient history book "Zhou Li", it is recorded that "on the passage from the frontier to the hinterland of various countries, a beacon tower is built at intervals, one after another. There are oranges on the stage, and there are cages full of firewood on the heads of oranges. When the enemy invaded, the beacon tower set off fireworks in succession to convey the alarm. Every night, the watchman lit the firewood in the cage and held it high, calling it a "lighthouse" to convey information to the leaders. During the daytime warning, the firewood piled up on the stage is lit, and the smoke is used to indicate the urgency, which is called "embarrassment". In order to make the smoke straight without bending, so that it can be seen from a distance, the ancients often used wolf dung instead of firewood, so it was also called wolf smoke. The Zhou Dynasty stipulated that when the emperor raised a bonfire, local governors must immediately lead troops to rescue and fight against the enemy. It can be seen that the implementation of the beacon system means that a huge and perfect military information contact network has appeared as early as last week.
I thought I heard a flying pigeon passing a book.

Depends on what it's for.
Send letters:
Ordinary people mainly rely on passers-by, monks, literati and other people who travel around the world to deliver letters. These people send messages to solve the problem of accommodation on the way, and they are also very willing!
The official is mainly the post office.
Transmit military information:
The army must have full-time personnel in this field, as well as beacon towers and homing pigeons.

The accuracy of carrier pigeons is low, most of them are letters, but it takes several months. There are also 100 Li Express, 200 Li Express and 300 Li Express on horseback, but they are all very expensive. Generally, this kind of "express delivery" is mostly used for official letters.

The ancient way of transmitting information was about-
Yubang: The letter with feathers indicates that the war is urgent.
Chicken hair letter: generally used in folk.
Feather book: used to recruit soldiers.
Pigeons pass books: mostly used in courts, government officials and gangs.
Bamboo tube: dual-purpose, similar to the current envelope.
Rapid transmission: used to transmit urgent military information, commonly known as "passing the gold medal".

There are also military means such as bonfires/wolf smoke.

You can use a torch.
