What are the ancient ways of information transmission?

In ancient times, the ways of information transmission were: post station, flying pigeon passing books, letters and oral communication. 1, Post Station: It usually means that the postman rides a horse to each established post station to get the letter, and then changes horses to deliver the letter to the designated place. Post-horse relay is an early organized mode of communication. Later, a whole set of postpartum system was gradually formed. Especially in the Han Dynasty, the documents delivered were graded, and the documents of different grades should be delivered by special personnel and special horses in accordance with the prescribed order and time. Sending and receiving these documents must be registered and marked with time to show responsibility.

2. Flying pigeons deliver books: use carrier pigeons, tie the letter to the carrier pigeons' legs, and then release it, and the carrier pigeons will return to their original places and write letters with the carrier pigeons brought from where. 3, wolf smoke. Wolf smoke is a signal of fireworks lit at the beacon tower when the ancient border guards found the enemy. The most familiar allusion is Shangzhou Zhou Youwang, who lit the beacon tower and made the guests smile. He lit this bonfire to convey the enemy's invasion and needed the surrounding governors to come to the rescue. This is also often used in wartime, when there is an invasion from other places or when people call for help.

4. Letters: In ancient times, rich people also sent letters by special people. They will prepare their own chariots and horses, and then the servants will send the letters to the places where they need to be sent, while the letters of ordinary people without money are mainly sent by friends from hometown who are on business trips or come from afar. Of course, this mode of transportation is not as fast as the imperial court.

5. Word of mouth: In ancient times, there were some common ways of information transmission, such as rumors, storytelling or poetry, which were all transmitted in people's chats.
