What's the difference between government departments and directly affiliated institutions?

Generally speaking, the county bureau is a component or directly affiliated institution of the people's government at the county level. It was established by the local people's government, not the superior bureau, and directly led by the local people's government. There is no direct subordinate relationship or leadership relationship between the superior bureau and the county bureau, but a business guidance relationship. For example, Wuwei County Personnel Bureau belongs to Wuwei County People's Government, and the director belongs to the county government. In legal procedure, the post of director needs to be nominated by the county magistrate, approved by the Standing Committee of the County People's Congress, and guided by Chaohu Personnel Bureau in business. In addition, if it is not a government department, but a bureau or institution directly under the government, it is basically the same as a government department except that the director is not a member of the government and cannot attend the plenary meeting of the government (only attending). The appointment and removal of the director does not need to go through the National People's Congress, as long as the people's government at the same level writes it. For example, Wuwei County Sports Bureau belongs to institutions directly under the government.
