The specific analysis is as follows: First, users should pay attention to the official WeChat official account of their province, which is usually named after "Health+Province Name", such as "Healthy Zhejiang". In the official WeChat account, users can enter the "Birth Registration" page through menu items and log in to the online registration platform for birth services. Next, users need to click "Birth Registration" to enter the registration homepage and select "Declaration Registration". In this link, users need to fill in the personal information of the woman and the man, including name, marital status, ID number, etc. Subsequently, the user needs to fill in the couple's marriage and pregnancy, such as marriage registration information, child birth registration number and so on. It is usually appropriate to choose the place of registration and the place of registration with the man's household registration, and sign a "commitment letter for the registration of maternity services". After filling in the commonly used mobile phone number correctly, the user submits the registration information. After submission, users will receive SMS notification to remind them to apply for birth certificate. If successful, users can print their own birth certificate and verify its authenticity by scanning the QR code on the certificate.
