Should I buy social security at my own expense?

Legal analysis: people who buy social security at their own expense are mainly aimed at people who have no fixed work units. Because they don't have a fixed work unit, no unit takes the initiative to pay a normal social security for them. At this time, I really have to consider buying social security at my own expense. Because social security is the guarantee of our daily life and old-age medical care.

Legal basis: Article 64 of People's Republic of China (PRC) Social Insurance Law includes basic endowment insurance fund, basic medical insurance fund, industrial injury insurance fund, unemployment insurance fund and maternity insurance fund. In addition to the basic medical insurance fund and maternity insurance fund combined accounting, other social insurance funds are accounted for separately according to social insurance types. Social insurance funds implement a unified accounting system throughout the country.
