You can't use the new rural cooperative medical system as social security.

Yes, there are two kinds at the same time, so you can only use one.

"Farmers voluntarily participate in the new rural cooperative medical system" is the fundamental policy of the new rural cooperative medical system. "The whole family must participate in the new rural cooperative medical system in accordance with the provisions of these measures", that is to say, they cannot participate in the new rural cooperative medical system as individuals, but they should take "households" as units, but each place has its own specific policies. As for whether it is true that "one person can't enjoy the new rural cooperative medical system" in your place, I feel that your situation should be special and you should be allowed not to participate in the new rural cooperative medical system. You'd better ask your local management department and tell me your details.

If you really strictly implement the policy of "no one left behind", that is, the policy of "there must be no less than one person in the family in Que Ning", then you can pay. A few tens of dollars a year is not much. After all, there are still several people in your family who want to enjoy this policy.
