I am 49 years old. Can Yanting buy personal social security?

Social security is a general term,

Social security in a narrow sense includes medical insurance, pension, unemployment, work injury, maternity and employee medical insurance. This social security cannot be paid, and its payment subject is the unit.

Social security in a broad sense also includes personal social security paid by individuals and social security paid by freelancers.

Personal social security only includes urban residents' medical insurance or new rural cooperative medical system and residents' pension, and cannot participate in paying unemployment, maternity and work-related injuries.
