Beijing, Tianjin, and Hebei have jointly launched a platform for sharing and utilizing people's livelihood archives, which went live on International Archives Day. This innovative platform facilitates swift cross-provincial inquiries into marriage records and the issuance of corresponding certificates. As China's first centralized cross-provincial data archive inquiry platform, it supports convenient nearby inquiries and one-window processing of essential people's livelihood archives within the Beijing-Tianjin-Hebei region.
