Does Chongqing have a Z intermediate fitter's license, and is there an extra pension?

No, the pension is a part of the service remuneration paid to employees in one lump sum or several times after retirement. It has nothing to do with the intermediate fitter certificate and will not be paid extra. Pensions are generally paid by the state finance or local finance, and the retirement benefits of retirees who have not participated in the social pooling of endowment insurance.
