Chongli in Zhangjiakou, north China's Hebei Province, first made its name with Winter Olympic ski runs. Now, with cool summers and a wealth of outdoor activities, this mountain town is writing a new summer chapter. CGTN host Julian Waghann and Mexican traveler Juan Carlos Cheang Guzman came to explore. They tried mountain biking and discovered the sustainable model of "winter skiing, summer cycling." At an ultra-trail race, runners pressed forward through pouring rain, their headlamps flickering like stars across the night. The Olympics may have ended, but the venues are far from dormant. They power new vitality for Chongli's all-season sports and cultural tourism.
