The criminal investigation technical department of the public security organ collects the photos and biological samples of the adoptee and compares them with the "National Information System for Public Security Organs to Find Abducted/Missing Children". After searching and comparing, it is confirmed that their biological parents cannot be found, and the public security organ will take them back to the local police station and issue the Report Certificate for Picking up Abandoned Infants (Children).
