Marriage insurance is education fund insurance. Education insurance, that is, old-age security or annuity insurance, has the dual functions of insurance and savings. Parents pay premiums for a certain period of time every year. When children need money for school in the future, they will take out the money according to the insurance contract. Usually, children receive an education fee every year from high school to college. After graduating from college, they can take out the money at one time, which can be used for their children's marriage, further study or business expenses. Therefore, it is necessary to buy education insurance.
