Took this photo when I was visiting the Shanghai World Financial Center some time ago, which is the second-tallest building in the world. Just I was appreciating the panoramic views from the very top of the building, the window cleaners appeared seemingly from nowhere. They were hanging right outside the building, with the very basic safety equipments, cleaning the windows. As you can see from the buildings at the background, that’s how high up they were hanging. I very discreetly snapped this shot of the youngest man of the 3 mainly because I didn’t want to distract him from his work. The man seemed only to be in his 20s, but he appeared to be very experience at what he was doing. All the tourists, including myself, were completely amazed and astonished at this. All comments welcome.
