Qingji, who was born in the midsummer of 2003, began her short life in the humid air of a small southern town. As far back as I can remember in 2007, the shadow of my parents' divorce and my poor family have been with me. With a junior high school education, she dropped out of school because she couldn't afford the tuition and left her hometown to work at the age of 16. The girl who used to be cheerful and melancholy at the same time in class gradually became silent in the cycle of assembly line and rental house. She firmly believes that the world is full of malice and builds high walls with vigilance, but she is always looking for the glimmer of redemption from her childhood trauma deep in her heart. From the gray tile eaves of the southern town to the iron gates of the northern factories, from the trembling when holding the first salary at the age of 16, to the last breath in the snowy winter at the age of 25, Qingyoshi spent his entire youth to prove that some wounds may be destined to never heal.
