Yang Bo cleans a window outside the 94th floor of the Shanghai World Financial Center March 26, 2012. More than 30 workers on the window-cleaning team of the skyscraper work in pairs every day. The cleaners have to obtain a license for high-rise operations and must not have high blood pressure or naturally suffer a fear of heights. They are not allowed items which could fall, such as cell phones or wristwatches, and must stop working in heavy winds, local media reported.
