Beijing, August 5 (Youth.cn) - On August 3, 2025, in Harbin City, Heilongjiang Province, in the heart of summer, as dusk began to tinge the sky, a vivid purple sunset slowly unfurled along the horizon. By the Songhua River, the twilight glowed faintly upon the dome of heaven, seeping gradually into the drifting clouds. This lavender radiance lingered low, softly diffusing, draping the world in a tender veil of light. Photo/CFP
