BERLIN, Feb. 16 (Xinhua) -- "Girls Always Happy", a Chinese female feature film which depicts mother-daughter relationship, premiered on Friday at the 68th Berlinale.

The film, directed by a young Chinese female director, Yang Mingming, as her first feature film, was nominated for the "GWFF Best First Feature award".

"Girls Always Happy" is a humorous psychological portrait of a fragile mother-daughter relationship. The heroin, starred by Yang herself, is a screenwriter in her mid-twenties and lives with her mother in a traditional but run-down one-story house in one of Beijing's hutongs.

Their unhealthily-close relationship is characterized by reproaches and quibbling, but only during meals do they appear to lay down their verbal weapons.

Yang Mingming said at the press conference held after the premier, the story was based on her own relationship with her mother and during playwriting she found lots of her female friends maintaining similar relationships with their mothers.

"It's not a panorama, but a portrait of mother-daughter relationship through specific actions of hurting each other as well as subtle love, through which the interpersonal relationship of the entire society is displayed," Yang said.

The 68th Berlinale kicked off on Thursday, and 19 films will compete for the best picture award, the Golden Bear, and other individual awards, the Silver Bears this year. "Girls Always Happy" belongs to the Panorama section of the Berlinale.
