My wife paid social security, but not maternity insurance. Do you like it? Besides, I also paid maternity insurance.

Social security is "five risks", including maternity insurance. Maternity is paid by the employer for employees, and individuals do not pay. After the unit has handled maternity insurance for employees, employees can enjoy maternity insurance benefits. If the spouse of an employee who enjoys maternity insurance does not participate in maternity insurance, he can enjoy maternity insurance benefits in accordance with state regulations. Therefore, if the company has paid maternity insurance for you and your wife has not participated in maternity insurance, your wife can enjoy your maternity insurance benefits.
