What are the ways in which ancient people and modern people convey information?

In ancient times, people had to make a special trip to inform each other when they first delivered news. Later, according to the different messages to be transmitted, a variety of transmission methods gradually emerged: beacons, post posts, records and printing.

Most of the beacon towers built in the Ming Dynasty were important military communication facilities to prevent foreign invasion in ancient times, and its main role was to transmit military warnings. Beacons are usually built on high ground, which can detect the enemy situation in time and quickly transmit information. Firewood, grass, sulfur, and saltpeter are always available on the beacon tower, and when the enemy situation is discovered, smoke is released during the day, and fire and artillery are set off at night, and the defense line for thousands of miles can quickly transmit the enemy's situation, and it is a defense communication network with a strict system.

The post office is very similar to the current postal communication, mainly the news is transmitted by special personnel in the form of letters. In ancient times, the best means of transportation used to transmit messages was the fast horse, but the horse's physical strength and running distance were limited, and the transmission of the distance required a change of horse, therefore, a horse station was established on many roads, which was a post station that played an important role in Chinese history. The function of a post office is like a modern post office, carrying all kinds of information and mail, and it is the lifeblood of a country.

We all know that the famous marathon run originated in ancient Greece, but few people associate it with the transmission of messages. Legend has it that in 490 BC, the Persians invaded Greece and lined up at Marathon. Athens immediately sent a messenger named Pelipides to Sparta, 150 kilometers away, to ask for help, however, the messenger brought back bad news that there were no reinforcements to the people of Marathon, and the Greek people finally defeated the Persians.

The messenger ran back to Athens from the marathon with the good news of victory, shouted the good news of victory, and died. Later, in order to commemorate him, people kept the marathon as a competition.
