Liu Yiting helps her grandma clean the fallen leaves in Jinan city, Shandong province, on Nov 30, 2014. Six-year-old Liu lives with her grandparents and a sister in a sanitation worker's dorm in Jinan. Her parents divorced four years ago and haven't come back for a long time. She was rejected by schools because she doesn't have her parents' labor insurance and her grandparents have no official right of custody. [Photo/cfp]
