傍晚的牆邊，推著單車的人笑得很鬆

Tall 9:16 frame. A Vietnamese man in his mid-thirties stands beside a bicycle on a city street in warm evening light, seen at eye level and framed from the waist up. He faces the camera with a friendly, relaxed gaze and an easy smile, his face centred in the upper third with the whole head well inside the frame. Build: wiry, medium height. Features: light tan skin, straight black hair swept to one side over a short undercut, a thin moustache, and a small scar through his right eyebrow, which is on the left of the frame; a plain black cord bracelet stays out of frame. He wears a plain charcoal crew-neck cotton t-shirt, and his forearms and hands stay outside the frame. A plain dark-framed bicycle leans on the wall at the lower right, and the street behind him falls away into warm soft focus with one lit window. Low sun from the left crosses his face, while the pale plaster wall behind him lifts the soft shade on his right cheek. The t-shirt and bicycle are plain and unmarked, and no shop signs or lettering appear. Photographic spec: a real natural-light portrait made with a full-frame sensor and an 85mm perspective, moderate depth of field, fine low-noise texture. One broad window-shaped daylight source comes from the side and models surfaces through a long light-to-shadow gradient, with weak reflected daylight keeping shadow detail open as brightness recedes. Fine pores and material texture stay optically clear. The finish is restrained, with neutral-warm midtones and gentle highlight roll-off.
