Why is Zhumadian social security paid in citizens' homes?

Social security acceptance business of citizens' home: social insurance registration (change) of employers (municipal institutions and enterprises above the municipal level) and qualification review of individual workers (including deferred payment of over-age personnel). These are all businesses that citizens' families can handle. Therefore, citizens can pay social security, in addition to citizens can also pay social security through designated banks, but also through the tax window. Hope to adopt.
