If you pay for it yourself, what you generally need to pay is pension, medical care and unemployment. Work injury and maternity insurance are not required.
If you pay by yourself, you have to bear all the expenses yourself. Now it is generally more than 900 a month.
I can't stand maternity insurance, and I can't make up for medical care, because medical care can only be paid from scratch. Medical care takes 20 years to enjoy a lifetime, and pension takes 15 years.
One disadvantage of social security is that, for example, after receiving a one-month pension, no one is left. The state only gives 5,000 funeral expenses, and the rest is given to the state, but the family members can't get it.
