Bank of China Tower (367m Triangular Prism)

Why was it built this way? Architect I.M. Pei composed the 367m tower from four emerging triangular glass-and-aluminum prisms inspired by bamboo shoots. Structurally, this three-dimensional space-truss transfers gravity and typhoon wind loads onto four massive corner columns, resisting extreme wind velocities while saving nearly 40% of structural steel compared to conventional rigid frames.

The Unbroken Feng Shui Thread: Despite its structural brilliance, the razor-sharp triangular edges and X-braces created giant Cleaver Blades (Jiao Sha / Corner Blade Sha) aimed straight at neighboring buildings. Aerodynamically, sharp prism edges slice coastal winds into high-velocity turbulent vortices that buffet adjacent facades. In response, Government House planted a dense screen of willow trees (Wood element buffering Metal Sha); HSBC mounted two cannon-shaped maintenance cranes on its roof aimed back toward the blade (Metal neutralizing Metal); and Li Ka-shing's adjacent Cheung Kong Center was designed as a balanced square fortress clad in four-sided reflective glass to deflect the cutting angles.
