Ai Weiwei mourns Hong Kong freedoms but ‘proud’ of Tiananmen photo furore

Ai took his offending picture of Tiananmen Square in 1995. It kicked off a series now known as Studies in Perspective. Wherever Ai went in the world he would take a similar photograph with a middle finger extended, usually towards something politically powerful or culturally important. He has done it in more than 100 locations, including outside the White House, Germany’s Reichstag and Russia’s Kremlin.
