Panjin, Liaoning province, has spent 10 years restoring wetlands and building a model for the harmonious coexistence of humans and nature.

The number of bird and mammal species living in the local wetland increased from 283 in 2010 to 304 at the end of last year, including red-crowned cranes and spotted seals.

Last year, Panjin was named the World Wetland City by the International Wetland Federation because of its progress in wetland protection.
