On the autumn equinox morning, as day and night are equally divided, Beijing gradually awakens in the crisp air. The sun rises slowly from the east, draping the city in a warm golden glow. Chang’an Avenue stretches like a straight golden line, dividing Beijing into northern and southern halves. Along the street, tall buildings and ancient structures stand in harmony, blending modernity with history. Chang’an Avenue is not just a major thoroughfare but also a time tunnel linking the past, present and future.
