China has over 20 million "empty-nest" youths (young people living without their families) aged 20 to 39, and most of them live in major cities, according to a report. Beijing, Shenzhen, Shanghai and Guangzhou are home to the biggest number of empty-nesters. They are young singles who live alone to work usually in cities.
People with "empty-nest" syndrome used to refer mainly to the elderly whose children have moved out from their homes. The term's definition has been stretched in China as more young folk live alone away from their hometowns.
