In the humid and foggy Qingchuan County, 17-year-old sports student Gao Ran runs on a cracked plastic track day after day. After his parents divorced, his father went to work in the south. He followed his grandmother Yang Juxiang, who suffered from diabetic retinopathy, and lived in a dormitory in an old textile factory. The ripped sneakers, brown sugar water in the morning mist, and insulin injections scattered on the window sill constitute the youthful gray-blue background of the boy.
Purpose: Missing grandma and making up for regrets
