How can I get the health code back after someone else has handled it?

You can only get it back if you reapply. Take Wuxi as an example, the details are as follows:

1, directly in the WeChat search window, select the official WeChat account of Wuxi Public Security Micro Police to enter.

2. At this point, continue to click Xikang code to jump.

3. If there is no problem, choose your own Xikang code.

4. Next, you need to click Reapply.

Please submit my information immediately after you finish.

6. In this way, you will get the results shown in the figure, and you can realize the requirements.
