Why does Tianjin Health Code fill in the information?

As soon as the Tianjin health code is opened, the information will be filled in. Because I haven't logged in for a long time, I need to fill in the information again. Information reporting can be carried out in the following ways:

1. Open the mobile phone WeChat, click Pay to enter on my page, and select City Service to enter.

2. After locating the city to the current city, click on the epidemic prevention and health code, then select the applet to view the health code, select the national government service platform, and select the applet in the city to apply for the health code.

3. After entering the applet, you need to log in and register first, check I have been authenticated, click Allow, then agree to authorize your mobile phone number, name and ID card information, enter the payment password, and complete the SMS verification.
