It’s an ode to nature and a reminder that humankind is not merely a spectator of nature,but also a part of it.the horizon evokes nature.It evokes something vast,the air too,the cyclical nature of days...so a circular movement.

Xie Xin talks about the horizon line that seperates the earth from the sky,life from death,the real from the unreal.This is the imagery she puts forward to give meaning to our movements.She ofen mentions the soil,the earth;I think she sees it as an ally,as an aid to us in our efforts to bounce back or to land gently.
