Recently, the weather is getting warmer. Under the warm sun in the spring, the Yellow River beside the ancient town of Lanzhou Hekou is constantly “busy”, with flocks of red ducks, mallards, ducks, and swans waiting for birds, foraging and playing in the river water. In recent years, with the continuous improvement of the ecological environment in the upper reaches of the Yellow River, migratory birds in Lanzhou have been increasing in number and population.
