Ai Weiwei's foreman looks remarkably similar to Ai himself, so much so that when people see him (the foreman, that is) there is the kind of communal, hushed stirring that happens around a possible celebrity sighting: Is that—? No, it couldn't be…is it though? The disappointment when the truth is revealed: no, it’s not Ai Weiwei. The man in question turns out to be one of four of Ai’s employees who have traveled from China to the States on his behalf.
