In this photo taken on March 1, 2010, Lu Keqian speaks while checking his website at his home in Liuzhou, China. When professors in China need to author research papers to get promoted, many turn to people like Lu. Working on his laptop in a cramped spare bedroom, the former schoolteacher ghostwrites for professors, students, government offices _ anyone willing to pay his fee, typically about 300 yuan ($45).
