BELGRADE, Sept. 19 (Xinhua) -- A solemn atmosphere of respect, sorrow, and reflection filled Belgrade's landmark building MTS Dvorana Thursday evening, as hundreds of Serbian and Chinese filmgoers, officials, and history enthusiasts gathered for the premiere of Chinese wartime film "Dead to Rights" (Nanjing Photo Studio). The screening, accompanied by a photo exhibition of rare wartime images, commemorated the 80th anniversary of the victory in the Chinese People's War of Resistance Against Japanese Aggression and the World Anti-Fascist War. Set largely in a photo studio, the film examines survival, loyalty, and the duty to preserve truth. On Dec. 13, 1937, Japanese troops captured the then Chinese capital Nanjing, starting six weeks of devastation that killed an estimated 300,000 civilians and unarmed soldiers. Chinese Ambassador to Serbia Li Ming, addressing the audience before the screening, emphasized that the film is based on authentic footage of the Nanjing Massacre.
