My WeChat was blocked, and I logged into another WeChat, but when I applied for the Shandong e-health password, it showed that the user already existed. What should I do?

Because you have registered WeChat, many apps now need real-name registration system, so it will show that you already exist. Now that it has been blocked, you can consult the backstage service staff of WeChat to help you find out the reason, and, um, see how to unblock it in advance, and then continue to use the original WeChat.
