What are the ancient, ancient, modern and contemporary ways of information transmission?

(Post-delivery system) In the Western Zhou Dynasty, in order to meet the needs of the contact between the king of Zhou and the vassal states, a post station was set up every 30 miles on the avenue, which was responsible for delivering official documents, receiving officials and transporting goods.

In the Song Dynasty, all official documents and letters were called "delivery", and "express delivery shop" appeared. There is a bronze bell tied to the collar of the riding whistle in a hurry. Running on the road, ringing the bell during the day and lighting a fire at night, the person killed is not responsible. Shopping for horses, shopping for people, rain or shine, day and night. In the early years of Southern Song Dynasty, Yue Fei, an anti-gold general, was forcibly recalled to Lin 'an from the front with 12 gold medals by Song Gaozong. This kind of gold medal is a gold plate sent by express delivery, indicating urgency. There are also bells and drums, fireworks, pigeons, semaphores, wolf smoke and other ways to convey information.
