The former mansion of the leader of the local Chinese community of Medan (then Deli) who succeeded in ingratiating himself with both the Indonesian Muslims and the Dutch colonial authorities. No mention is made of his relations with the local Indian community. He became very rich on the profits of his hard-working countrymen, importing them as labour for Dutch plantations and shipping them off when they became destitute or impoverished through overwork, old age or opium. This colourful and ornately decorated building tells his story and that of his descendants, as well as filling in some details about the city's past.
