Once Upon a Time

The TV drama Once Upon a Time, adapted from a novel of the same name, was a hit since it was released in January this year.

The film version, starring leading actor and actress Yang Yang and Liu Yifei, will premiere on August 4.

The story centers on the romance between two gods Bai Qian and Ye Hua in a mythical world. By post-80s female writer Tang Qi, the original novel is an inspiration from Classics of the Mountains and Seas (Shan Hai Jing), China's mythological collections.
