Tropical animals escape cold with customized intimate services in south China's Guangxi How do hippopotamuses, giraffes and other animals from tropical areas cope with the cold in winter as the recent minimum temperature in Nanning, south China's Guangxi Zhuang Autonomous Region, sharply dropped to only 6 Celsius degrees? These animals have been provided with customized intimate services to escape the cold at the zoo in Nanning. A giraffe warms itself by the fire.

Meanwhile, Siamese alligators gather together to enjoy "sunbathing" and sometimes climb into the pool to soak in the "hot spring.” In the primate park, ring-tailed lemurs either huddle together or sit around electric oil heaters, while giraffes in the breeding area warm themselves by the fire while leisurely "tasting" fresh leaves.
