Xu, Li-Xian’s ‘Stairs’: Using the circular arch, a distinctive feature of NTU’s architecture, as a structural element for the sculpture. Four identical components, at different heights and angles, form a multiple rhythmic structure. From a single circular shape, it becomes a complete sculpture through combination. The dynamic lines ultimately become straight lines, representing a fair and impartial attitude towards dealing with things. It symbolizes students having rules after receiving education, and excellent students, after collaborative integration, can achieve success.
