Career
I. From New Hui to Macau
Born in New Hui, Guangdong in 1837, Lou Kau fled to Macau as a refugee in the 1860s and built up small businesses before accumulating real capital.
II. Farming the gambling taxes
Under the Portuguese administration's tax-farming system, Lou Kau acquired the fantan and pak-kop-piu concessions, becoming the largest Chinese merchant of late-Qing Macau.
III. Cross-sector expansion
Gambling-tax revenues were reinvested into banking, pawnbroking, real estate, and shipping, forming a cross-industry network. He completed the Lou Kau Mansion in 1889 — today one of the most intact Chinese mansions in Macau.
IV. Family litigation and tragedy
In 1907, beset by family lawsuits over his estates, Lou Kau took his own life.

Contribution to Macao
Lou Kau's commercial empire across gambling, finance, and real estate gave Macau's late-19th-century Chinese merchant class real economic weight to negotiate with the Portuguese administration. The Lou Kau Mansion, now managed and opened to the public by the Macao Cultural Affairs Bureau, anchors his personal story into the city's collective memory as one of the most significant Chinese-style buildings in the UNESCO Historic Centre.
