Some parents in less developed areas prefer boys to girls. So they don’t offer girls a good education. In order to give people comfortable lives, China’s government has taken some measures to control the population. One is known as the one-child policy.

My village was like a big family. But the only shortcoming was that I couldn’t go shopping in big stores unless I travelled for a couple of hours.
