As the city transforms, one art teacher quietly preserves its soul with her brushstroke. In recent years, Lanzhou art teacher Zhang Ying has dedicated herself to capturing the city's disappearing old buildings, preserving street scenes marked by time on her canvas. Zhang Ying creates realistic paintings that meticulously document architecture. Each stroke preserves more than scenery, it keeps the warmth and memory of home. As time rushes forward, her art leaves the city a treasured visual archive.
