Visitors feed gulls at the Haigeng Park in Kunming, southwest China's Yunnan Province, Feb. 11, 2003. Urban parks in China offer easy place for people to relax and unwind. Furthermore, China's urban parks feature more less-impact exercise equipment and ways to have fun for young and old. With the breeze blowing and boats floating in the parks, people enjoyed dancing, singing and folklore performance from 1950s to 1990s. Nowadays, people have more choices of activities in the parks, like the fashion show by the elderly locals and the low expense wedding ceremony for the young people. These typical scenes of China's urban parks not only mirror the changes of people's leisure life, but also show the social development in miniature, as China is building ecological civilization and promoting the harmonious coexistence between humans and nature.
