Chinese documentary films are likely to embrace a brighter future, as the recent documentary film "Twenty Two," following "Return to the Wolves" and "Earth: One Amazing Day," both of which were box office successes and got strong reviews, Guangzhou Daily reported on Aug. 21.

The film "Twenty Two," which tells the story of surviving Chinese "comfort women" hit 120 million yuan ($18 million) at the box office by Aug. 21, topping the list of Chinese documentary films.

The 90-minute documentary featured 22 "comfort women" in China, who peacefully shared their eyewitness accounts of history.

"It is not a movie that sells pain and tears. It is just enough to bring the audience to them, to see them, and to get to know them. Understanding them is the biggest help. They have their own way to take in the pain," said Guo, adding that in order to survive, they seldom recall those bitter memories.

Due to lack of capital for shooting and promoting the film, as well as the sensitivity of the topic, the film was not viewed with a promising future. Director Guo Ke even had to raise money through crowd funding to finish production.

However, many famous Chinese actors and directors have called on the public to watch the film at cinemas to show support for Guo and to pay tribute to the women who are now in their 90s. Some online celebrities also bought tickets and invited their followers to watch the film for free.

The film was a success and got strong reviews, signifying that documentary films in China are increasingly recognized by audiences.

In addition, Chinese documentary films have achieved success for their premium and pure content, which move audiences and arouse their emotions, as well as increasing demand for different types of films.
