The concept of the layout of this case comes from the jade on the knot, and the concept of jade also echoes with the Emerald City. The shape of this case is relatively square, and there is a large atrium space in the middle, which resembles the shape of Fangzheng emerald in image; it is adjacent to the mountain park on the east side, and the undulating shape of the mountain park is like a winding rope knot, tied to the crystal on the west side. The transparent jade also implies that the future development of this case will become a local landmark like jewel jade.
