Why is Yuhang's supernumerary treatment good?

Equal pay for equal work. The supernumerary staff of public institutions, that is, temporary workers, pay insurance, and some units even get equal pay for equal work as the wages of regular staff. The salary is good. Non-supernumerary and non-supernumerary personnel refer to those who are recruited by the employer, rather than those who are organized by the organization department or the personnel bureau for examination. Non-staff and non-staff personnel can usually be divided into workers, contract workers and temporary workers.
