The Tower of Hope:

The overall form is inspired by the merging of a bow and arrow and a spinning shuttle, referred to as "the fleeting of time".The top part of the tower is designed with elements that remind viewers of a Chinese pagoda. From top to bottom, the exterior is separated into four layers: light, sound, color, and water, each layer representing a different aspect of time. The most special feature of the artwork is the water clock at the bottom. The clock is designed by French physicist Bernard Gitton, and has both scientific and artistic elements. The water clock has mechanical precision, and Although the flow rate of the fluid changes, the clock is still capable of calculating time through the swinging of the pendulum. The fluid of the design has two roles; it maintains the swing of the pendulum while displaying the hours and minutes.

Armillary Sphere：

An instrument used for astrology in ancient China, the Armillary Sphere is made up of three layers of circling loops, namely the Sphere of the Six Cardinal Points, Sphere of the Three Stellar Objects, and Sphere of the Four Movements. The unique connected structure also implies the connectedness of various scientific knowledge.
