Is it a fresh student who only pays the housing provident fund and does not pay social security?

Not exactly. According to the national civil service examination network, graduates who pay five insurances and one gold and do not pay social security are not fresh graduates. Graduates of ordinary colleges and universities recruited by the state who leave school and fail to implement their work units during their career selection can be treated as fresh graduates if their household registration, files and organizational relations remain in the original graduate school, or if they are in the competent employment departments of graduates at all levels, talent exchange service agencies at all levels and public employment service agencies at all levels.
