On the south bank of the Yangtze River, a unique wetland ecosystem breeds a variety of fish and aquatic animals. Every autumn, this wetland attracts nearly 700,000 migratory birds (such as cranes and other rare bird species) for the winter.
They live in harmony with lakes and fields, creating a beautiful picture of nature. However, due to the complex terrain of the wetland and the huge number of migratory birds, it has been extremely difficult for local staff to manually take care of the reserve.
