文摘The ageing of society has been considered as one of the three major social problems in the twentyfirst century. Since 2000, China has entered the ageing society formally, and become one of the earliest developing countries that witness the population ageing, and also the countries with the largest ageing population in the world. Problems for supporting the aged have become crucial social problems of China. This paper, on the basis of analyzing changing physical and mental characteristics and needs of the elders, proposed different living models such as living together, living alone, living close, and social nursing facilities.
