Xiamen, formerly called Amoy, was one of the first Chinese cities to become a Special Economic Zone in the 1970's, boosting development and opening Chinese companies to the outside world. Over the past decades, Xiamen has become a destination for Chinese tourists thanks to its mild climate, beaches, and colonial buildings. EPA/ROMAN PILIPEY
