Hot pot is the most popular food year round in Chongqing and for the pandas at the city's zoo, it's no exception, except their hot pot was just a little bit different. Zoo keepers at Chongqing Zoo spent two days building a bamboo replica 'hot pot' to serve to the zoo's four three-year-old giant pandas - except this one was served cold and stuffed with watermelon, bamboo shoots, carrots and other delicacies.
