Children raise the national flag at the "Kubeiland" teenage experience base in Changsha, Hunan province on May 27, 2010. "Kubeiland," a replica of a real city and micro-society, offers more than 70 different kinds of "jobs" for children to perform role-playing tasks.  Children are encouraged to take on a variety of roles from a chef, doctor, firefighter to journalist. They can learn how to manage the money they earn. The base covers some 10,000 square meters, and more than 150,000 children have visited in the past five months. [Photo/Xinhua]
