The Audit Bureau and the Finance Bureau are generally municipal or county-level units, and such units are only recruited when the local provincial examinations are held, so the situation in different regions is different, and there must be more regions and fewer regions. The tax bureau includes national tax and local tax, and they also include the tax inspection brigade. The demand for personnel is much higher than that of audit and finance, so there are relatively more people recruited. Generally speaking, the recruitment of civil servants, the public security system, the judicial system and the tax system are all large households, and auditing and finance belong to government departments and do not occupy much space.
