Why can't I find an e-card in the card pocket in Su Meng's office?

Maybe you haven't opened the e-cert yet.

To open the electronic certificate:

Take the Certificate of Change and Correction of Household Registration Items as an example. Users enter the business processing page, read the processing guide, click "declare", and the basic information such as the applicant's name and ID number has been pre-filled by the system, so they can manually enter the change correction certificate information. After selecting the collection method, you can submit the relevant information, and the staff will issue the e-certificate after it is approved in the background.
