Jiao qu de niao

Some ground subsidence has occurred in a suburban area and a team of engineers, including Hao, is dispatched to investigate the cause. After days of wandering around in the empty suburb looking for answers and carrying his heavy gear, Hao walks into a primary school where he finds a diary chronicling the story of a boy and the separation of what seems to be an intimate group. As the investigation keeps going, Hao discovers that this diary might contain prophecies about his own life. - IMDb
