Before traveling to Europe for about a fortnight, I cycled along some old residential places in Beijing. Actually, they are not old by normal standards. But they have become rare here, while land has become incredible expensive. They are not in good condition either, and would be costly to renovate; not even to think of the "opportunity cost" versus putting a few high rise buildings there. They are not Beijing Hutongs, which have been partly accepted to be a heritage, and they are neither "useful". So, they are neither seen as heritage, nor are they viewed as something of value. Their time has come.
I decided to come back with a camera and take a few snapshots. I was lucky, because when I returned today, some of them were already demolished (the satellite photo underneath still shows the blue roofs which show that this was a more recent development) . They are/were along the canal, outbound the city, beyond the 4th ring. Please refer to the co-ordinates in the grid below for exact location.
