A 13-year-old boy is walking on a grassy field. In winter, the grass has just sprouted and there is a thin mist on it. In the morning, the rosy glow shines and the morning mist lingers. A little bird flies from the grassland. The countryside and landscape are poetic and picturesque, with cinematic effects, high image quality, light and shadow effects, side backlighting, 8k, Zhang Yimou.
