Bank of China Tower Hong Kong: I.M. Pei's "Feng Shui Knife" and Its Lasting Legacy

Rising among the skyscrapers of Central Hong Kong, the Bank of China Tower stands unmistakable — a triangular prism with sharp, distinct edges thrusting skyward like a blade. Designed by Chinese-American architectural master I.M. Pei, this building is not only a triumph of modern architecture but also the center of one of Hong Kong's longest-running Feng Shui debates, spanning decades.

I.M. Pei and the Bank of China Tower

The Bank of China Tower (中银大厦) was constructed between 1989 and 1990 to serve as the Hong Kong headquarters of the Bank of China. Its designer, I.M. Pei (贝聿铭), is a Pritzker Prize laureate whose portfolio includes world-famous works such as the Louvre Pyramid and the JFK Library.

Pei's design was inspired by bamboo — symbolizing "rising higher with each node" (节节高升). The tower's exterior consists of four triangular frameworks that taper as they ascend, mimicking bamboo segments climbing upward, conveying the meaning of "step-by-step advancement." From an architectural standpoint, this design is structurally ingenious and aesthetically beautiful — a paragon of modern architecture.

However, from a Feng Shui perspective, the Bank of China Tower's sharp angles ignited enormous controversy.

The "Feng Shui Knife"

The most distinctive Feng Shui feature of the Bank of China Tower is its sharp edges. The triangular framework creates multiple sharp lines along the facade, running from bottom to top like the blade of a sword.

Feng Shui masters believe these edges generate intense Sharp Corner Sha (尖角煞, jian jiao sha) — wherever the sharp lines point, they "chop" like a blade, creating harmful rushing energy toward whatever building lies in that direction. Since the Bank of China Tower has sharp angles on all four sides, it effectively "wields knives in four directions," emitting Sha Qi toward surrounding structures.

Bank of China Tower's Edge Direction	Targeted Building	Feng Shui Effect
West-facing edge	HSBC Building	"Knife chopping HSBC"
Other directional edges	Surrounding buildings	All directions affected
Topmost edge	Sky	"Piercing Heaven" energy

The most famous "victim" was HSBC. The Bank of China Tower's west-facing edge points directly at the HSBC Building, creating the infamous "Knife Chopping HSBC" scenario. According to legend, shortly after the Bank of China Tower was completed, HSBC's performance temporarily declined — which Feng Shui masters attributed to the chopping Sha.

HSBC's "Cannon" Response

Facing the Bank of China's "knife attack," HSBC summoned Feng Shui masters to devise a remedy. The final solution: install two large window-washing cranes on the rooftop of the HSBC Building, shaped conspicuously like two "cannons" — using "cannons" against "knives" to create a standoff arrangement of "knife versus cannon."

This arrangement may appear coincidental (the cranes are functional equipment after all), but in the eyes of Feng Shui masters it was perfectly calculated — "cannons" belong to the Fire element, while "knives" belong to Metal. Since Fire controls Metal (火克金), the "cannons" can effectively subdue the Sha Qi of the "knife."

Reportedly, after the "cannons" were deployed, HSBC's performance rebounded, and the "knife-cannon standoff" became the most iconic Feng Shui image in Central Hong Kong.

Adversaries	Building	Feng Shui "Weapon"	Element
Bank of China Tower	Wields the "knife"	Sharp Corner Sha from edges	Metal
HSBC Building	Mounts the "cannons"	Rooftop cranes	Fire
Controlling relationship	Fire controls Metal	Cannon subdues knife	Resolution

How Other Buildings Responded

Beyond HSBC, other Central buildings each adopted their own Feng Shui countermeasures against the Bank of China's "knife Sha":

Building	Countermeasure	Feng Shui Principle
Cheung Kong Center	Four-sided "shield" design	Shields block the knife
Legislative Council Building	Domed roof design	Curves dissolve sharpness
Statue Square	Open space	Emptiness releases Sha
Street-level shops	Hanging Bagua Mirrors	Reflect Sha Qi away

Cultural Context: In Feng Shui, the concept of "defensive architecture" emerged in Hong Kong's competitive commercial landscape. When one prominent building emits Sha Qi, neighboring buildings must respond — creating an ongoing "energy dialogue" between structures that has shaped the city's skyline in ways no Western city has experienced.

The Cheung Kong Center's "shield" design is especially clever — with square yet rounded corners, each side can "block" the Sharp Corner Sha without actively attacking (unlike HSBC's "cannons") or passively suffering harm. It represents the most "balanced" approach to Sha dissolution.

I.M. Pei's Stance

Faced with criticism from the Feng Shui community, I.M. Pei's personal attitude was intriguing. As a Western-educated modern architect, he did not subscribe to all Feng Shui claims, but neither did he dismiss them entirely.

Pei once stated that the Bank of China Tower's design was inspired by bamboo, symbolizing "rising higher with each node" — a positive meaning. As for the Sha Qi generated by the sharp edges, he believed it was largely a psychological effect.

However, some reports indicate that Pei did incorporate certain Feng Shui considerations during the design process — for instance, adjustments were made to the building's base and entrance orientation based on Feng Shui advice. This demonstrates that even an internationally renowned architect could not ignore Feng Shui factors when designing buildings in Hong Kong.

Pei's Feng Shui Attitude	Expression
Design inspiration	Bamboo rising — positive symbolism
On Sha Qi claims	Believes largely psychological
Practical adjustments	Base and entrance orientation consulted Feng Shui
Overall position	Not fully believing, but not dismissing

The Bank of China Tower's Feng Shui "Gains and Losses"

From a Feng Shui perspective, the Bank of China Tower's "gains" and "losses" are both remarkably clear:

Gains:

• The form soars upward like a "blade piercing heaven," projecting commanding authority;
• As the tallest building in Central at the time, it "looked down from above" with a dominating presence;
• The bamboo-segment motif symbolizes "rising higher with each node," signifying progress and advancement.

Losses:

• The Sharp Corner Sha radiates in all directions, making "too many enemies" and creating isolation;
• "Wielding the knife" harms others — powerful yet lacking harmony, making it difficult to gather Qi sustainably;
• The sharp form belongs to the Metal element; excessive Metal becomes brittle and easily breaks.

Bank of China Tower	Gains	Losses
Form	Commanding presence	Creates too many adversaries
Height	Dominates from above	Isolation invites vulnerability
Symbolism	Rising step by step	Rigidity leads to snapping

The Tension Between Feng Shui and Architectural Aesthetics

The Bank of China Tower case reveals the inherent tension between Feng Shui and architectural aesthetics:

From an architectural standpoint, the Bank of China Tower is a masterpiece — structurally innovative, beautifully formed, and positively symbolic. I.M. Pei's design received widespread acclaim from the international architectural community.

From a Feng Shui standpoint, the tower's sharp angles genuinely generate Sha Qi — whether or not you believe in Feng Shui, when every surrounding building adopts defensive measures, this "Sha" becomes "real" in the cultural-psychological sense.

Cultural Context: This tension is not irreconcilable. In fact, since the Bank of China Tower's completion, architects working in Hong Kong have increasingly embraced the principle of "balancing aesthetics with Feng Shui" — pursuing modern design appeal while avoiding obvious Feng Shui problems. The tower's "cautionary tale" has, in a sense, driven Hong Kong's architectural profession toward greater "Feng Shui awareness."

What Happened After

After the Bank of China Tower was completed, the Bank of China's business in Hong Kong continued to develop steadily. Judging by "results," the Bank of China did not decline because of "wielding the knife" — instead, it established itself "through authority" in some sense. This may suggest that Feng Shui's "Sha" is not necessarily harmful to the building's owner; rather, it more often affects surrounding buildings.

This raises an intriguing question: Who does Feng Shui's "Sha" actually harm? Does it hurt the one emitting the Sha, or the one being struck? The Bank of China case appears to support the latter interpretation — the "knife-wielder" remains unscathed, while the "chopped" party must seek remedies. Of course, this is only one case's interpretation, and Feng Shui practitioners hold varying views on this matter.

Key Feng Shui Concepts

• Sharp Corner Sha (尖角煞): Harmful energy formed by a building's sharp edges, believed to rush toward the targeted building and cause misfortune.
• Fire Controls Metal (火克金): A principle from the Mutual Generation and Restriction (相生相克) cycle — "cannons" (Fire) can subdue "knives" (Metal), making it a common approach to dissolving Sharp Corner Sha.
• Curves Dissolve Sharpness (以圆化尖): Using rounded designs to neutralize Sharp Corner Sha — the circle still belongs to Metal, but does not form a "pointed spike."
• Bamboo-Segment Design (竹节造型): An architectural motif symbolizing "rising higher with each node," considered a positive Feng Shui symbol.
• Feng Shui Awareness (风水自觉): The trend of proactively considering Feng Shui factors in modern architecture — the Bank of China case helped drive this trend.

Quick Tips: Recognizing Sharp Corner Sha in Everyday Spaces

• Look up at neighboring buildings: When choosing an apartment or office, check whether nearby buildings have sharp edges pointing toward your windows or entrance
• Check your interior: Even inside your home, sharp corners from furniture (like exposed counter edges or pointed décor) can generate minor Sha Qi — soften them with rounded cushions or plants
• Use natural barriers: Tall, leafy plants near windows can help deflect rushing energy from external sharp corners
• Bagua Mirrors (八卦镜): For severe cases of incoming Sharp Corner Sha, a Bagua Mirror placed on the windowsill can reflect Sha Qi away
