National Geographic China's Lost Girls

Due to cultural, social and economic factors, traditional Chinese preference leans toward boys, so girls are often hidden, aborted, or abandoned. As a result, tens of thousands of girls end up in orphanages across China. Today, more than one quarter of all babies adopted from abroad by American families come from China. Lisa Ling joins some of these families as they travel to China to meet their new daughters for the first time. Along this emotional journey, she shares in the joy of these growing families and also witnesses firsthand China's gender gap, its roots, and its possible repercussions.
