At the Crane Breeding Base of the Liaohekou National Nature Reserve in Panjin City, Liaoning Province, more than ten young red-crowned cranes with light brown feathers are roaming the grassland. With their fluffy heads, round bodies, and long legs, they walk unsteadily, curiously exploring their surroundings. Behind these lively and adorable young cranes lies the dedicated care provided by the staff day after day.
