Deep in the vast snowy forests of the Greater Hinggan Mountains, the Ewenki people protect an ancient tradition that has lasted for thousands of years. As the pen gate slowly opens at dawn, a flood of reindeer rushes toward the snowfield – this is both a release of wildness and a demonstration of the wisdom of the symbiosis between humans and nature. Through their "semi-wild herding" method, they let reindeer forage and thrive in the wild, while maintaining a deep connection with this land.
