What's the difference between imperial, imperial, imperial and internal security in ancient China?

There is no difference, just different names.

The imperial army was an army subordinate to the emperor in feudal times and served as a guard for the emperor or the palace and capital.

Due to the differences of times, cultures and regions, there are other synonyms, such as guards, guards, guards, guards and so on.

After the decline of the feudal era, these names often became military honorary titles, which were awarded to troops that established special achievements.

In modern times, except for some countries with constitutional monarchy, orthodox guards were retained. Other countries that were not ruled by kings in name, such as democratic countries and socialist countries, all had military forces similar to "gendarmerie" or security forces.
