Historically, the traditional "four big families" of Hong Kong—who rose to prominence during the mid-20th century through shipping, banking, and early trade—comprise the Li (Bank of East Asia), Ho (Robert Ho Tung lineage), Hui (Hui Oi-chow), and Lo (Lo Cheung-shiu) families. In contemporary economic discussions, the term is frequently applied to the modern real estate and commercial dynasties that dominate the city's property sector, specifically the Li Ka-shing family, Kwok family (Sun Hung Kai), Lee family (Henderson Land), and Cheng family (New World Development).
