Let's introduce the answer to the question about the difference between your department and your unit.
1. Conceptually, the definitions of "department" and "unit" are different: conceptually, unit refers to an independent organization or institution, and department refers to the functional part of an independent organization;
2. In terms of nature, departments and units are different in nature: units are relative to individuals, and units are generally legal persons, which are relatively complete and independent social organizations. A department usually refers to a certain type of unit with the same or similar nature. Of course, departments can also refer to the working institutions within a unit and the working departments of the government, such as the Ministry of Communications and the Ministry of Personnel.
3. From the perspective of scope, the scope of departments and units is different: the scope of units is very wide, including not only functional departments, but also people's governments at all levels themselves, as well as agencies or functional departments of people's governments at all levels. Strictly speaking, in state organs, departments refer to the functional institutions of people's governments at all levels, such as public security bureau, industrial and commercial bureau and sometimes industrial and commercial departments. It is an institution that performs the functions and powers entrusted by law and is an integral part of the government. However, there is no absolute comparison between the "ability" and "unit" of a department, and they are all relative. Some departments have many units, while others have few units. On the contrary, some units are made up of many departments, while others are made up of fewer departments.
