Is it necessary to buy health insurance? How does it compare with social security?

Social security is the foundation, and serious business illness is the supplement. Social security is paid to you in proportion, which is enough in most cases, but it is still not enough in the face of some major diseases. For example, social security allows you to report 75%, which seems high, but when you face hundreds of thousands of medical expenses, the remaining 25% is enough for you. In this case, you can apply for 25% commercial insurance.

Insurance gambling is a probability. Whether it is necessary to buy or need this answer mainly depends on your personal economic strength and risk tolerance.
