The male lead, who lost his job and his wallet, is trapped in an old alley of the old city, living a difficult and hard life. Uncle Zhang repairing shoes at the alley entrance, Sister Wang at the grocery store, Granny Li living alone, and Xiao Zhou delivering newspapers show no blunt pity, but hide clumsy and delicate care using only a passing enamel lunchbox.
