What should I do if the number of health card binding cards exceeds the limit?

The certificate binding of the health system exceeds the limit, in fact, because your ID card is a multi-account real-name registration system, so your real name will exceed the limit. Try it first. Ask this question with a customer service bill of lading, preferably manual customer service. Don't wait for the robot to reply. If online manual service can't help you, call the customer to find a manual solution. This method can restore normal use.
