Great insight on people asking where you live. It's similar in Korea. In a lot of cases they are asking indirectly whether I live in a rich area and in turn whether I can afford to live there. I look poor, so asking where I live is a way of making admit my low status in public (i.e. humiliating me in public). If someone asks that to me, I choose to remain silent or ask them why they are asking, while steeling myself to leave or protect myself. I often leave by saying I have to go to the bathroom or make a phone call, and just ditching the person.
