To bring this film to life, Fang, along with a dedicated film crew, embarked on a transoceanic journey that spanned the UK, Canada, the US and Japan.

They met with eyewitnesses and descendants, gathering and curating an extensive collection of invaluable historical documents and visuals.

Their efforts were aimed at recreating the dramatic rescue operation with as much authenticity and respect as possible, ensuring that the narrative is both compelling and true to the events that unfolded.

"We have tracked down over 380 descendants of the survivors, conducting more than 130 in-depth, face-to-face interviews," Fang said.

"Our team has also amassed an extensive archive of historical photographs. It is our ambition to weave these fragments of personal narratives and visual records into a comprehensive tapestry that authentically represents the full scope of history," he added.

Prior to this, the valiant acts of the Dongji fishermen had seldom reached a global audience.

"During my interviews with the descendants of the fishermen, a common refrain was that their forefathers felt they were merely fulfilling their duty when they spoke of the rescue," Fang said.

"Conversely, the descendants of the POWs invariably conveyed deep gratitude and reverence for the Dongji fishermen. These fishermen, with their heroism, bravery and humility, deserve to be honored," he added.

The documentary was pre-screened last year in London, Bournemouth, Edinburgh and several other places in the UK, and will be put on public release in China on Sept 6.

"I'm confident that once this film is aired across the country, it will bring to light the story of this small island and shed light on the events that transpired here 82 years ago," Fang said.

Having been bestowed the title of "Honored Islander" of Dongji, Fang spoke with heartfelt emotion.

"This honor is not just a recognition from the residents of Dongji, but also a profound validation of the film's significance," he said. "I hope the audience will be inspired to visit Dongji more often, to really soak up the local culture and the warmth of its people. I'm sure as they explore, they'll feel the weight of the history that this island holds."
