It's no secret China wants to keep a clean image during this year's Olympic Games, held in Beijing. So what does a country do with run-down areas of the city that look horrible? The simple answer is build a wall to hide it.
...the 8-foot brick wall Chinese authorities have erected down the south side of Luomashi Boulevard, obstructing a row of rundown storefronts...Walls like it have been built in many parts of the bustling city, as some 500,000 foreigners have come to town for the Games - part of the government's pursuit of perfection, albeit sometimes a Potemkin perfection, in the way the ancient capital presents itself to the world.
