The Temple of Heaven is the home for many animals: the slender squirrels are stocking winter rations, the Hedgehogs here already knows that cat food is the new option, crows are accustomed to flying to Beijing's urban in winter, and long-eared owls and kestrels find new destination in Beijing's country parks. The well-developed root system is the guarantee for ficus virens to get rooted in the hilly city Chongqing in southwestern China. Macaques in the plateau city Guiyang started to have new foraging habits in close contact with people. Purple Mountain in Nanjing provides the best place for fireflies living.
