A combined photo shows cats wander around Forbidden City. The cats are seldom seen in visitors' areas, but according to Ma Guoqing, who works at Forbidden City, cats have been living inside the palace since ancient times, and some of the cats there now are direct descendents of the original palace cats. Some others are strays, but they are taken good care of at Forbidden City. They can also help control the rat population. [Photo/Chengdu Business Daily's Sina Weibo account]
