Paper short abstract:

GS brings a new development model between socialization and traditional family elder service. It features with functions of day-care for elders and night-post for volunteers, which constructs circulation of "I serve for others' parents and others for my parents" and realization of elder service for free.

Paper long abstract:

Background: The aging in China is deteriorating with TER of 1.2 under policy of"one child"and"later-marriage and later-childbearing".Now elders'population is more than 0.2 billion and is expected to exceed one-third of total population in 2033.Unattended elders are left in hometown and their children work far away. The situation is challenging Chinese traditional elder-care model which all family members were living together and elders were cared by their children.

Proposed countermeasures:

①Establishmenting GSs in communities to provide service to elders.Meanwhile,GSs can serve as night-posts for volunteers and some elders.

②Establishmenting volunteer service mechanism and feedback system in GSs to provide services for volunteers and their parents/grandparents.

③Establishing"Ginkgo Hand-in-hand Card"(GC)system to bind volunteers and their parents/grandparents,which could be managed nationwide.

Feasibility: The existing public service carriers could be reconstructed in short time with low cost by governments supplemented by companies.

①relying on Community-Health-Service-Center and other public facilities.

②relying on nationwide social-security-card with additional function to Community-Health-Service-Center for remote access.

③boosting tourism with public welfare of Hand-in-hand Travel and cheap safe travel of night-posts.

Significance: "Ginkgo" is a holy tree worshiped for human life in ancient time to represent endless vitality. GSs can harmonize families and society.The model of"I serve for others' parents and others for my parents"could meet needs of empty-nest elders and society to benefit all people.It can keep sustainable development strategy of elder-care for it would be a non-financial solution and a model to motivate nationwide participation in social eld-care service.
