As the first snow falls, Northeast China Tiger and Leopard National Park is transformed into a world of ice and silver, where every creature begins its winter struggle for survival. Siberian tigers adapt their hunting strategies to the snowy terrain, while Amur leopards enter a unique breeding season amid the cold. Across the forest, herbivores such as sika deer search for food along sunlit slopes, using instinct and wisdom to endure the harsh season. In this vast forest, nature reveals its most profound law: survival, adaptation and the balance of life.
