From July 4 to 8, Bắc Ninh Province is collecting more than 13,000 DNA samples from relatives of unidentified fallen soldiers, the largest campaign of its kind ever conducted in the province.

Part of the nationwide 500 Days and Nights Campaign, the initiative aims to build a national DNA database to help identify the remains of war martyrs and fulfil the long-held wish of countless families to bring their loved ones home.

With support from police officers, local authorities and volunteers, elderly and infirm relatives are guided through every stage of the process, while mobile teams visit homes and hospitals to collect samples from those unable to travel. The campaign combines modern DNA technology with a deeply humanitarian mission to restore the identities of those who sacrificed their lives for the nation.
