Can individuals pay maternity insurance to the Social Security Bureau of Baotou City, Inner Mongolia?

At present, the Ministry of Human Resources and Social Security of our country stipulates that employers must participate in maternity insurance for employees in accordance with regulations, and both men and women must participate in maternity insurance. However, individuals cannot purchase maternity insurance and can only purchase commercial maternity insurance. At the same time, some cities in my country stipulate that urban and rural medical insurance participants can be reimbursed for maternity medical expenses.
