Li is ten years old and lives in an apartment block in Beijing, China, with her parents. She is an only child—as a result of the Chinese government’s “one child per family” policy, introduced to control population growth. Families with more than one child are usually penalized. Li goes to a school nearby, where she enjoys learning math, singing, and music. She is a perfectionist and will spend up to three hours each night completing her homework to the highest standard. She also attends ballet classes twice a week after school. Three times during her school life, she will have to attend a compulsory army summer camp organized by the People’s Liberation Army. In preparation for this she has to attend army training. Li does not want to be in the army when she grows up. She wants to be a policewoman so that she can protect people.
