What does comprehensive social security mean?

Are you talking about the comprehensive medical insurance in Shenzhen?

Comprehensive medical insurance is applicable to

① On-the-job personnel with Shenzhen household registration;

② Retirees who have registered in Shenzhen before reaching the statutory retirement age do not receive pension insurance benefits on a monthly basis.

In addition, the employer can handle comprehensive medical insurance for its non-Shenzhen registered employees;

The payment base is the same as the salary base for Shenzhen registered employees to pay endowment insurance premiums. The proportion of payment is 4.5% for the unit, 2% for the individual and 5% for the person under 45. 5.6% of non-retirees over 45 years old are included in personal accounts.

Individual social security contributions are as follows:

1, deep households: pension, comprehensive medical care, unemployment, regular or contract workers can participate in the housing provident fund;

2. Non-deep households: pension, hospitalization or comprehensive medical care or migrant workers' medical care and unemployment insurance.

I don't know what you mean by general insurance.
