Beijing is a mega-city with a larger population，and also has deeper degree of aging. In recent years，paying more attention to the “bed side” of the family life，the “side” of community care and the “surroundings” of streets （townships） daily life，which is considered to be “three-sided” service demands，Beijing has strengthened the construction of the “four-level” service security system of city-level guidance，and has maken great progress. In fact，the street （township） care centers for the aged play an important role，since it not only undertakes six functions：institutional pension，community care for the aged，home help for the elderly，skills training，professional support and information management，but also plays the role of “two ends in the middle” by coordinating family，community and other service resources in result to meet the multiple personality needs of the elderly and improve their feelings of gaining and happiness as well as security. In the process of development，we are also faced with various difficulties which have both commonalities and individualities，such as planning，land，legal person，tax，talent，capital，etc. Therefore，we should especially study and discuss services for the elderly further more with the deepening of reform and development.
