Usually you don't feel social insurance has much presence.

But when you actually need to see a doctor, get hospitalized, have check-ups, or pick up medicine, that's when you realize how important it really is.
Many people usually feel reluctant to pay the premiums.
But once you're actually admitted to the hospital, you'll discover that social insurance isn't optional.
It's the trump card that helps you cover expenses when it matters most.
To put it plainly:
You can delay buying a car.
You can buy two fewer outfits.
But don't let your social insurance lapse.
