Can I leave my child's account in Dongcheng District Talent Service Center?

You can't.

According to China's household registration management system, Dongcheng Talent Service Center cannot settle down for its children in registered permanent residence. After the child is born, the household registration is generally declared by parents or other legal guardians. If you need to settle your child in the household registration, it is recommended that you contact the local public security bureau or household registration management department to understand the specific settlement policies and procedures.

To settle down is to register in a certain place and settle down for a long time. To settle in a place, you need to meet the conditions stipulated in the place of settlement and go through certain procedures before you can settle in that place.
