As China marks the 80th anniversary of victory in the Chinese People's War of Resistance Against Japanese Aggression and the World Anti-Fascist War, a new documentary has been released which aims to tell the full, true and panoramic story of the war, and highlight the sacrifices made by the Chinese people at that time.

"Mountains and Rivers Bearing Witness," which released nationwide on Aug. 15, is produced by China Central Newsreel and Documentary Film Studio (Group). Director Han Jinna, who co-directed the film with general director Yu Peng and directors Huang Yue, Zhang Ning and Li Yan, emphasized its commitment to authenticity.

"The most distinctive feature of this film is its authenticity," Han said. "All footage is genuinely captured — not fictionalized film or television drama. The power of truth is what moves and touches people most profoundly."

Han described the project as a solemn duty to utilize the studio's unique archive of historical footage.

"At this particularly significant moment, China Central Newsreel and Documentary Film Studio (Group) recognizes its responsibility and obligation to produce this film," Han said. "As the archivist and custodian of this historical footage, our studio possesses invaluable visual materials dating back to the Yan'an Film Troupe period. This unique advantage makes it our honor to undertake such a responsibility at this time."
