Animals help campaign to reclaim land

A caged lion is on a playground in Zhengzhou, Central China's Henan province on April 11, 2010. The lions, tigers, emus and sheep were dispatched by the city's zoo to join in the zoo's campaign for the return of this 50-mu land, which was lent to the Henan provincial sports bureau 26 years ago for bicycle racing, following the recent rumor that the bureau is developing the land for commercial use.
