"Hide and Seek" - Hide and Seek with Shadows: This is a childhood memory Xiao Feng shared at a friend's gathering. It happened when he was a few years old, more than twenty years ago. In the neighborhood where he used to live, an abandoned factory, like a ghost town forgotten by time, was a playground where Xiao Feng and his friends often went to explore. The factory building was riddled with holes, graffiti and traces of time crisscrossing the walls, large chunks of plaster peeling off to reveal the damaged brick and stone structure beneath, like scars that had been torn open. Weeds grew wildly, swaying wildly in the wind.
