Perhaps no one knows the power of imagination better than Chinese sci-fi writer Liu Cixin. Until four years ago, Liu worked full-time as a computer engineer at a power plant in Yangquan, Shanxi province. He only wrote science fiction in his spare time. But it was during this time that Liu’s imagination took flight. He did what he might never have the chance to do in real life – wander in space, fight with aliens, and visit planets light-years away.
