Where can Luoyang get the qualification certificate of international social work?

Government affairs service center. I hold the original valid ID card to the window of Human Resources and Social Security Department of Luoyang Administrative Service Center to get the certificate. The processing time is from Monday to Friday (except holidays) from 9: 00 am to 12: 00 am and from 13: 30 pm to 16: 30 pm. Social worker card is the abbreviation of social worker's professional level qualification certificate.
