Why did the ancient bandits dare not rob the "800-mile express"?

I believe everyone knows that there were 800 Li urgent letters in ancient times. But what exactly is 800-mile express? We all know that there were post stations in ancient times. There is a post station about every twenty miles, and the average speed is 300 miles a day. If you encounter something particularly urgent, you are limited to 800 miles a day. Therefore, in case of special emergency, every post station uses the best horses. How to deal with particularly urgent situations, such as very important things or information that is very important in terms of intelligence, such as where there is rebellion or where there is war. So when this happens, it must be urgent.

Everyone knows that people like bandits make a living by hijacking things. Idle around every day. That is to say, if the bandits are in urgent need of 800 miles. Why can't they hijack it?

First of all, the reason why bandits dare not hijack 800 urgent letters is because once such letters are hijacked, they are capital crimes. And it is likely to involve family members. And the government will arrest you no matter how much manpower and material resources it uses. In the face of life, even bandits cherish their own lives. And they are more afraid of implicating their families. So hijacking 800 urgent letters is harmful rather than beneficial to them.

The second is. Generally speaking, 800 urgent letters are related to national security. Because many times, where there is rebellion or where there is war, there is news. Bandits are also people of the country. They know that those letters are related to national security. If these letters cannot be delivered. It is likely to be related to the life and death of this country. So they don't usually think about hijacking these letters.
