The inspiration for this work comes from a short stories named<fog> of the Chinese avant-garde female writer: Can Xue. This story tells of one day our room was full of fog. fluff grew all around me. My mother was crazy. My brothers couldn't walk and they already beyond 20 years old. Dad tied my brothers to his belt and flung them around. One day my mum went outside never came back I find her everytime, and I know she is around...
