What do you call an ancient investigator in China?

The ancient scouts were called "scouts", which originated in the Han Dynasty and were named after the princes directly under them. They are divided into cavalry and infantry, and are usually served by agile sergeants. They are very important weapons. Scouts used to be people who specialized in observing the enemy's situation on the frontier. Shang Shu Yu Gong: "Scouts say they are in danger and wait on thieves."

Also known as "reprimand", it was the ancient Ministry of War of China. Exclusion: degree, distance. The ancient road log, a small green monument erected on the right side of the road for calculating mileage, is erected every five miles. Before the pre-Qin period, Qianhou was responsible for checking all dangers and protective facilities, waiting for an opportunity to catch thieves. After the Qin and Han Dynasties, this post was no longer set up in the army, but scouts who went out to spy were called scouts. After the Tang and Song Dynasties, scouts were no longer called scouts, but were renamed horse scouts or spies according to the different equipment uses of "ma bu" or horse stance just look reconnaissance. Ming Shi said: "There are more than 500 huts (around) called scouts to watch the enemy advance and retreat." The so-called "reprimand, measure" and "wait" means wait. "

Scouts are mobile scouts, mainly responsible for reconnaissance against the enemy and reconnaissance against the enemy. However, because the division of labor in ancient times was not so detailed, scouts did more than just spy on the enemy. For example, in the army, he also wants to inquire about the news near the battlefield, the terrain and geographical environment, the drinking water source, where the feasible road can be drawn on the military map, and whether to find pioneers to open the way to meet the water. And they are better at fighting and weapons than others, and they are also very good at hiding. In the team, the scout's role is to quietly solve the sentry, sneak behind enemy lines, steal important documents or assassinate enemy leaders, which are all his work scope. So scouts now have the role of special forces. It was not until later that the division of labor was refined that the terms spy and assassin came into being.
