C han Tan Ching-fen is the matriarch of the family that controls Hang Lung Group, a major real estate developer in Hong Kong and mainland China. She is the widow of the company's founder, T.H. Chan, who established the group in 1960. After his death, their son, Ronnie Chan, took over as chairman and became the public face of the company, building it into a property giant.

Hang Lung Group is renowned for its portfolio of high-end commercial properties, particularly its successful '66' brand of luxury shopping malls in major second-tier cities across mainland China, such as Shanghai, Shenyang, and Wuxi. While her son Ronnie leads the company, Chan Tan Ching-fen and her family trust remain the largest shareholders. Her immense wealth is derived from her inherited stake in the vast and valuable property empire her husband founded and her son significantly expanded.
