The Vuong family mansion is located in a valley in Sa Phin hamlet, Sa Phin commune, surrounded by mountains. It was once the residence and workplace of the renowned Hmong leader Vuong Chinh Duc, who was respectfully called the “King of the Hmong” by locals for his leadership over a vast area of the rocky plateau. With its unique architecture rich in historical and cultural imprints of the highlands, the Vương family mansion is considered a symbol of past power and the rise and fall of a once-prominent Hmong lineage in the country’s northernmost region.
