Zhou Yu's Train.

Zhou Yu, a ceramic artisan in China's rural Northwest, has a deep rapport with Chen Qing, a shy sensitive poet. Taking a long train ride every weekend just to make mad passionate love with him, her longing seems insatiable. Until one day, she meets the hedonistic vet Zhang Qiang and begins a torrid affair, which takes her to another train station, and another level of lust. Driven by the locomotive of love and desire, she hustles through a dark tunnel of no return.
