If the education guidance center is located in the Education Bureau, it is a department of the Education Bureau. Its status is the same as that of teaching and research section, personnel unit and education section, and its staff are civil servants.
If it is set up separately, it is not directly under the control of the Education Bureau, and it is likely to be a public institution. Institutions are also financial allocations and iron rice bowls.
If it is opened by some people in the society, it is an enterprise, and all the people who go in are ordinary wage earners.
To distinguish which one it is, it is very simple to look at its superior unit.
