Officers hold slogan placards for urban management

Urban management officers hold placards in front of street vendors, who occupy a lane in a road, trying to persuade the vendors and their customers to move away from a street in Wuhan city, capital of Central China's Hubei province, on the night of May 16, 2012. The slogans on the placard politely warned customers that the food safety of illegal stalls is not trustworthy and advised sellers to move away. Such a move has been warmly welcomed, as China's urban management is often blamed for violent enforcement.[Photo/CFP]
