What social security is better to pay now?

Your question is very big. Social security includes a lot of contents. At least publishing a book is not a problem. I will simply answer it here.

Composition: social insurance = endowment insurance+medical insurance+industrial injury insurance+maternity insurance+unemployment insurance+housing accumulation fund.

The specific social security composition ratio is:

Endowment insurance: the unit pays 2 1% for you every month, and you pay 8% yourself;

Medical insurance: the unit pays 9% for you every month, and you pay 2% plus 10 yuan major illness co-ordination (major illness co-ordination mainly covers hospitalization);

Unemployment insurance: the company pays you 2% every month, and you pay it yourself1%;

Work injury insurance: the unit pays 0.5% for you every month, and you don't have to pay a penny yourself;

Maternity insurance: the unit pays you 0.8% every month, and you don't have to pay a penny yourself;

Housing provident fund: the unit pays you 8% every month, and you pay 8% yourself (the provident fund can be paid or not, because it is under the jurisdiction of the provident fund center).

Supplementary housing provident fund: the unit pays you 8% every month, and you pay 8% yourself (this is only available to state-owned enterprises with good general benefits, and the proportion is determined by the company itself, so it is very ethical for general companies to pay provident fund).

Tip: Social security in every part of the country is different, but the details are similar. If you want to know about your social security, I suggest you tell me where you come from next time you ask questions.
