Park fascinates us in a way that it contains the genes in the traditional culture of the recognition of the symbiotic relationship between nature and people, and the reflections on our own state of existence in the midst of the global ecological crisis. But more directly, an ideal park contains the spirit within an ideal city we believe: the space filled with nature that opens up equally to everyone; people, plants, and little creatures find their own space perfectly well; Life successfully seeks the chance to breathe with the nature altogether, the flower blossoms and fall, people come and go — everything happens naturally. OPEN has redesigned the "Yuandadu Ruins Park", hoping that the park city can start from the park around us!
