The 4K resolution film, "At This Moment: Celebration of 70th Anniversary of National Day," was released nationwide Saturday in Mandarin.

"The Mandarin version of the film landing in national cinemas will sure make a beautiful memory and be a powerful force for people to strive for a better future," Shen Haixiong, president of China Media Group (CMG) said at the ceremony.

The whole film is produced with 4K ultra-HD picture and 5.1 surround sound, and the pictures have been adjusted frame by frame.

The premiere also invited three flag-bearers from the National Day military parade to share their experiences participating in the big event. Children who sang at Tian'anmen Square on National Day also came to the event.

The premiere of the film was held by the CMG at Wanda cinema in Beijing.
