In the second episode of the Unsung Ally, amid the destruction of war, guardians of civilization never rest. From elderly Tokyo residents honoring victims of the Nanjing Massacre in song; to documentary director Cao Haibin restoring painful memories of the atrocity through his work; to Beijing academics who, in 1933, began risking their lives to protect national treasures; to teams in Hangzhou today using digital technology to revitalize Chinese heritage—generations have lived on, protecting truth and a cultural legacy. With ordinary strength, an extraordinary shared mission has taken shape: ensure that civilization endures the ruin of war and passage of time, with unwavering faith in a brighter future.
