The busy and non-stop city life day in and day out makes people always feel the time flying in a homogenized flow. Einstein's theory of time bending mentions that everything tends to go to the place where time passes the slowest - the gravitational force will pull it towards that place. If the ever-changing light in the natural wilderness is the center of slow gravity, then the greenway around the mountain and into the lake is the gravitational track that pulls people into the slow life. The exhibition invites the audience to slow down their steps, from the "green" source field to the "green" site, to unfold the cutting-edge planning strategies and future scenarios of joyful living, and to see how the 234 kilometers of the greenway can pull everyone into the wilderness, and inject the pulse of trees and stars into your life and ours.
