"I have over 30 reindeer now and mainly make money through selling velvet antlers, which are known for culinary and medicinal properties," Gu said. "In addition, as tourism has been booming in recent years and more people come here to experience Ewenki's Arctic culture, I can earn over 1,000 yuan ($143.9) per day during peak season in summer."

To revive reindeer culture and sustain increase in herders' income, local officials carried out tax-free policies and offered tents, recreational vehicles and daily supplies free of charge. With years of effort, the number of breeding centers has grown to 16 in operation, and the reindeer population witnessed a steady growth, from about 100 to 1,200.
