It must be a Vietnamese cultural thing, but seeing "patriarch" in the old man's introduction box seemed strange, instead of simply "father". When I saw the patriarch term, I expected it to be large premises where a whole clan lives, that is, multiple families or at least a very big extended family, possibly with servants, and the patriarch would basically be the (great) grandfather overseeing it all. In reality it was just a single middle-aged man and his daughter.
