Kwong Siu-hing is a Hong Kong businesswoman and billionaire matriarch of the Kwok family, whose wealth is rooted in Sun Hung Kai Properties Limited (SHKP, HKSE: 0016), one of the largest and most influential real estate developers in Hong Kong. She is the widow of Kwok Tak-seng (d. 1990), who co-founded SHKP in 1963.

Kwong's career is defined by her generational stewardship and fiduciary oversight of the colossal, publicly traded real estate empire. Her structural role has been crucial in maintaining family unity and control amid highly publicized family feuds and legal battles among her three sons (Walter, Thomas, and Raymond Kwok).

• Sun Hung Kai Properties (Major Shareholder & Former Non-Executive Director): The foundational source of her wealth, tied to the massive Hong Kong and mainland China real estate empire. She is the largest individual shareholder in SHKP.
• Family Governance: She successfully restored stability and family control after her eldest son, Walter Kwok, was ousted as Chairman in 2008.
• Investment Strategy: Her fortune is tied to the long-term hold and massive appreciation of prime Hong Kong commercial and residential real estate assets.
• Controversy: Her decision to remove her eldest son as chairman was one of the most high-profile corporate feuds in Hong Kong history.

Kwong Siu-hing's structural genius was her ability to stabilize the family empire during periods of internal turmoil. She served as Chairman of SHKP from 2008 to 2011, assuming the leadership role after her eldest son, Walter Kwok, was ousted (due to controversial mental health concerns and a falling out with his younger brothers). Her return to the chairmanship ensured a smooth transition and restored corporate governance.

She retired as Chairman in 2011, but remains the largest individual shareholder and a Non-Executive Director, exerting immense fiduciary and patriarchal influence. Her wealth is secured by the colossal, long-term, stable appreciation and cash flow generated by SHKP's vast real estate portfolio.

Kwong Siu-hing's social impact is structural, stemming from SHKP's role in shaping Hong Kong's urban environment and providing essential commercial and residential infrastructure. The family's foundations support various education, healthcare, and community initiatives.

Her structural contribution is tied to the successful generational transition and long-term stability of one of Asia's most important property developers, ensuring its immense influence on the regional economy.

Kwong Siu-hing maintains the traditional, composed style of a Chinese matriarch and corporate executive. Her attire is consistently formal and high-quality, favoring traditional Chinese business wear. Her aesthetic reflects stability and immense patriarchal authority, typical of a leader in the HK property scene.

Residing in Hong Kong, her luxury is the immense security and financial reward derived from her multi-billion dollar fortune. Her life is dedicated to real estate stewardship, corporate governance, and the long-term legacy of the Kwok family empire.
