The photos shot in mid-February show that Siberian tigers and other precious wildlife species are under careful protection in the Northeast China Tiger and Leopard National Park. The park, officially designated in 2021, spans an area of over 1.4 million hectares in the northeastern provinces of Jilin and Heilongjiang. Advanced technologies, including a space-air-ground integrated network system, facilitate the protection of the animals. Photos: Shan Jie/GT
