What does full social security mean?

That is to say, at present, employees have social security. Those who start their own businesses in cities can apply for flexible employment social security in terms of talents. Those who are unemployed in an old and small city can apply for social security for urban residents in the streets, and those who are unemployed can apply for social security for farmers in the villages.

In other words, no matter what your status and job nature are, there is a social security system that suits you (not to say that the state forces you to participate in insurance or gives you insurance for free). This is a social security system that provides different prices and different treatments for all kinds of people.
