A man wearing a mask walks along a street on a heavy hazy day during winter in central Beijing, January 30, 2013. Beijing temporarily shut down 103 heavily polluting factories and took 30 percent of government vehicles off roads to combat dangerously high air pollution, state media reported on Tuesday, but the capital's air remained hazardous despite the measures.
