一座大型热带温室项目,矗立在中国北方某地,似已停摆多年。一阵风吹来,在温室各处,现出了风的行迹。风吹过,一切复归原态,但也有什么东西随风而逝。 A vast tropical greenhouse project stands somewhere in northern China, seemingly abandoned for years. A gust of wind blows in, leaving traces of its presence throughout the greenhouse. Everything returns to its original state after the wind, yet something vanishes with the breeze.
