What are the benefits of social security for children?

Children's social security card is actually a medical insurance card, because children only participate in residents' medical insurance. The card will take effect after paying the premium every year (generally about 100 yuan). You can pay directly by card when you see a doctor. Although you have no money in your card, after you pay a certain amount (generally about 200 300 yuan), you will start to deduct it directly, as long as you pay 40%~50% of the medical expenses. To put it bluntly, medical treatment can be discounted.
