　　Dead To Rights, a film about the Nanjing Massacre during World War II, has maintained its dominance at China's summer box office, grossing over 1.5 billion yuan (about $210 million) within just 10 days of its July 25 debut.

　　Driven largely by the film's success, the nation's single-day box office revenue during the ongoing summer movie period from June through August hit a record 380 million yuan on Sunday, signaling a strong surge in market momentum, per data from ticketing platforms Maoyan and Beacon.

　　“Sunday's record box office performance has generated strong momentum for this year's film market and boosted industry confidence,“ said Yin Hong, vice chairman of the China Film Association and a Tsinghua University professor, in an interview with Xinhua on Monday.

　　The film has topped daily box office charts in all provincial-level regions across the Chinese mainland for seven consecutive days through Sunday. So far, it has attracted over 40 million admissions, reflecting its strong resonance with audiences.

　　Drawing on verified photographic evidence of Japanese wartime atrocities during the Nanjing Massacre,Dead To Rightstells the story of a group of Chinese civilians who seek refuge in a photography studio during the brutal occupation of Nanjing by Japanese aggressors in 1937.

　　In a desperate bid for survival, they are compelled to assist a Japanese military photographer in developing film, only to discover that the negatives contain damning evidence of atrocities committed by Japanese forces across the city. Determined to expose the truth, they secretly keep the negatives and risk their lives to smuggle them out to the outside world.
