1. First open WeChat or Alipay on your family's mobile phone, and then find the electronic health code page you applied for.
2. On the Electronic Health Code page that opens, click and select the Print Health Code icon.
3. In the opened "Health Code Printing" page, select the electronic health pass code to be printed (people who need to travel), and click "Save to mobile phone photo album" at the back.
4. Wait for the prompt "The health pass code has been saved to the mobile phone photo album" and the saved location path.
5. Go back to the phone desktop and open the phone "photo album", find the "WeChat" folder in the photo album, and find the "health password" picture just saved.

Matters needing attention
Please read the notes on the health pass carefully before going out.
Please note that the health certificate password is generally valid for 14 days, with the effective date on it. After the effective date, you must regenerate a new health pass code and print it again!
The health pass code needs to be presented together with the ID card.
The paper health pass code must be printed in color.
If passengers and their families need to travel together, just click "multi-code display" to show it to the inspectors.
