Which item of social security can't be broken?

If the medical insurance is broken off, the medical insurance will not be reimbursed from the second month. In other words, you can't enjoy the treatment paid by the medical insurance pooling fund. But the personal balance in the social security card can still be used! But it affects the payment term. If the medical insurance payment is interrupted only within 3 months, then the continuous payment can be counted as the continuous participation time; However, if it exceeds 3 months, the medical insurance period in personal social security will be cleared directly, but the medical insurance period in employee insurance can still be renewed.
