How fast was the ancient 800-mile express train? Why does no one dare to rob on the road? The so-called "eight hundred miles plus urgent" is a way for ancient people to transmit urgent information, which is generally used for information involving major national security. Usually must arrive within two days
Ancient transportation was not developed, and now there are no vehicles and other tools, mainly horseback riding, and the ancient 800-mile express is equivalent to more than 400 kilometers now. Horses are not machines on such a long journey, they run all the time, they are thirsty and tired, and the soldiers who pass by need to rest. Therefore, the ancients set up many stations where officials could pass on information and change horses again to continue to move forward. If there are any errors in passing the message, the penalties will be very severe.
The Tang Dynasty specifically stipulated that anyone who delayed intelligence for his own reasons would be sentenced to hanging. Generally, only information related to national security will be 800 miles urgent, and eight hundred miles will not carry too much silver and two. The imperial court would also attach great importance to it, such as being robbed by bandits on the road. The imperial court will definitely send troops to clean up, and even be exterminated, so no bandit is so stupid as to rob the road.
