On the Otog Grassland, the ancient horse-riding culture is thriving alongside modern lifestyles. Zhang Zhengguo's photo series captures this unique blend. The images showcase the warmth of rural life, with children playing and locals gathered to watch horse races. Meanwhile, they depict modern transformations, such as trucks transporting horses and motorcycles traversing the vast plains. These photos vividly document the enduring vitality of nomadic civilization across the passage of time.
