Thick, off-the-scale smog shrouded eastern China for the second time in about two weeks Tuesday, forcing airlines to cancel flights because of poor visibility and prompting Beijing to temporarily shut factories and curtail fleets of government cars. The capital was a colorless scene. Street lamps and the outlines of buildings receded into a white haze as pedestrians donned face masks to guard against the caustic air. Visibility was less than 100 meters (100 yards) in some areas of eastern China, the official Xinhua News Agency reported. More than 100 flights were canceled in the eastern city of Zhengzhou, 33 in Beijing, 20 in Qingdao and 13 in Jinan.
