Sungang Choochoo Garden is an innovative and practical project of micro-green space renewal and social governance exploration. Different from city parks, it provides a garden for people to share and participate in. With the concept of co-construction and sharing, it takes a garden as a bridge for neighborhood reconstruction. It not only realizes the micro-renewal of green space, more importantly, it transforms the abandoned space into an emotional field with social cohesion, enabling residents to have a sense of gain and happiness, and realizing the transformation from garden to home.
