This study indicates that adult sons＇ setting up their own homes is a precondition for elderly couples＇ becoming ＂empty nesters,＂ a situation which in turn leads to contracts for ＂care rotation.＂ Many factors, including marketization, the transformation of social structure and the rising status of daughters-in-law in family decision-making are responsible for elderly people＇s loss of their role in such decision-making. Therefore, during the life course of the elderly, ＂care rotation＂ is in fact an arrangement imposed on elderly parents rather than their own choice.展开更多
