The Equation of Love and Death

It tells the story of Li Mi (played by Zhou Xun), a Kunming cab driver who longs for the day she can be reunited with her missing boyfriend.

[4] Li Mi, a chain smoking taxi driver in the Chinese city of Kunming has been searching fruitlessly for her lost boyfriend for years.

The two men kidnap Li and force her to drive to a designated location, however midway on a refuel stop at a petrol station, she signals to the attendant to call for help.

The film ends with her finding out the fate of her boyfriend who left her a safe deposit box of money and a letter telling her to start a grocery store.

[5] Early reviews by western critics suggested that Cao Baoping's sophomore film was a stylish thriller/drama, but that much depended on the power of Zhou Xun's performance as Li Mi.
