Editor's note: As protection of the planet's flora, fauna and resources becomes increasingly important, China Daily is publishing a series of stories to illustrate the country's commitment to safeguarding the natural world.

Deep in the primordial forests of North China's Inner Mongolia autonomous region, the gentle chime of reindeer bells is the sound that defines a way of life.

For the around 300 Ewenki people who inhabit the Olguya Ewenki ethnic township of Genhe city, their bond with reindeer is one of the most specialized human-animal relationships in the world. Unlike larger nomadic groups in the Arctic who primarily raise reindeer for meat, the Ewenki use reindeer to transport household goods, for riding, for their milk, and as spiritual companions. Reindeer are deeply embedded in their culture.

For decades, this unique bond faced the threat of extinction as the lure of the city pulled the younger generation away. But today, the tide is turning. As 67-year-old elder Dekesha Kaertakun observes, the mountains are calling their children home.

"Between 2008 and 2015, my heart was heavy," said Dekesha. "I used to tell my peers that as long as there are reindeer in the mountains, there will be Ewenki to raise them. I had to believe that to stay hopeful."
