What is the difference between the open recruitment of many institutions organized by the Personnel Bureau and the self-recruitment of institutions?

The difference is definitely different. First of all, you should understand that institutions are divided into financial allocation institutions and self-supporting institutions. Most of the recruitment organized by the Personnel Bureau belongs to financial institutions, that is to say, financial institutions must submit recruitment quotas to the Personnel Bureau because of lack of personnel. After the examination and approval, the Personnel Bureau is responsible for the recruitment work, and receives the salary of financial institutions after the recruitment. Self-supporting institutions can openly recruit on their own, although they should be registered in the labor and employment department after the recruitment, but the wages will be paid by the self-recruiting units according to the relevant provisions of the local social employment wage standards and the actual situation of the unit. Generally speaking, the minimum wage cannot be lower than the average wage of the local unemployed in the previous year.
