Four actresses — Zhou Dongyu, Chen Yanxi, Liang Jing and Wu Mochou — lay on a bed dressed in pajamas to promote their latest movie, Run for Love, at a recent event in Beijing.

Actress Zhang Ziyi plays the lead in the film.

The movie, which focuses on love as a collective memory, opens in mainland theaters on Jan 15.

The film, co-directed by five art-house veterans, comprises five short romantic tales.

The five directors are Guan Hu (known for Taiwan Golden Horse-nominated Cow), Gao Qunshu (The Message), Zhang Yibai (Flee of Time), Teng Huatao (Love Is not Blind) and Zhang Meng (The Piano in a Factory).

The stories which involve lies, betrayals, loyalty and interdependence aim to examine how Chinese women see love in a modern society.

Xu Wen, the executive producer of the movie, said at the event: "Everyone has his or her unique take on love. To avoid just one personalized point of view, a team of directors will show audiences a varied understanding of love."
