The first three "Detective Chinatown" films have grossed more than 8.7 billion yuan ($1.2 billion) since the series launched 10 years ago. The films follow the boisterous private investigator Tang Ren, played by Wang Baoqiang, and his introverted, highly intelligent nephew Qin Feng, portrayed by Liu Haoran, as they tackle mystery cases in cities like Bangkok, New York and Tokyo.

"This time, we wanted to offer audiences a story that feels both familiar and fresh, so we chose a different longitudinal time period to offer a unique perspective," Dai said. He added that the film not only explores Chinatown's historical roots but also illustrates the prejudices overseas Chinese faced in 1900.

For the creative team, the year 1900 is a significant intersection in history. It was the Year of Gengzi in the lunar calendar, a year associated with misfortune in Chinese folklore. The year saw the peak of the Boxer Rebellion amid widespread chaos in China. The Qing dynasty also declared war on foreign powers but was ultimately defeated by the Eight-Nation Alliance, resulting in forced war indemnities.

In stark contrast, the U.S. was experiencing modernization and prosperity. Chinese immigrants moved to America in search of work, including jobs in railroad construction, but faced severe discrimination, such as the Chinese Exclusion Act. At the same time, the fictional detective Sherlock Holmes gained prominence as a cultural icon. "There were many stories and inspirations from that period for us," Dai said.

The leading characters are once again portrayed by Wang Baoqiang and Liu Haoran, but their new roles are entirely different from those in previous installments. Wang plays Ah Gui, a versatile Chinese descendant adopted by an Indigenous American tribe, while Liu takes on the role of Qin Fu, an extroverted practitioner of Chinese medicine. Set in San Francisco in the 1900s, the story centers on the murder of a white woman in Chinatown, for which a Chinese man is the main suspect. This shocking crime ignites public outrage, leading to demands to shut down Chinatown. The duo gets caught up in the investigation, racing against time to reveal the true murderer in a tense battle of wits and bravery.

As a long-time collaborator with Chen Sicheng, the mastermind behind the "Detective Chinatown" franchise, Dai — director of hits like "Endless Journey" and "Fireflies in the Sun" — described their collaboration in co-directing the film as seamless, owing to the deep mutual understanding they have cultivated over the years. He fondly recalled how Chen would frequently laugh and cry behind the camera during the shoot, describing him as a deeply sensitive person.

The most ambitious and challenging aspect of the film was constructing a 1:1 replica of San Francisco's landmarks from over a century ago in just seven months. This replica spans 200,000 square meters at Laoling Film Studio in Shandong province. Supported by the local government and enterprises, the project showcases China's remarkable construction capabilities. The replica is open to the public during the Spring Festival, giving visitors the chance to explore it after viewing the film.

Dai noted that the set is incredibly realistic, as the film's production design department conducted extensive research and collected historical documents to authentically replicate every detail of the props and the set from that era. This included constructing slopes that mirrored the actual geographical features of San Francisco. He added that foreign actors, including Hollywood veteran John Cusack, who stars in the film, were in awe of the replica town during filming.

The director expressed his hope that the film could serve as an important vehicle for promoting Chinese culture and also bring more resonance to overseas Chinese, while calling for the solidarity of Chinese communities abroad. Additionally, he hopes the film will inspire audiences to explore the history of China during that era. "When audiences engage with this history, they will see how strong we are today and gain a sense of confidence, perseverance and a commitment to continuous self-improvement," he said.

Dai said he was excited about the potential for future expansions in the "Detective Chinatown" universe, which could explore different timelines. "Anything is possible," he laughed. "As long as audiences continue to enjoy their adventures, we are eager to create more."
