"(CBS) The link between Martin Cohen's 30-percent fall in sales of stirrups in California to falling revenue in China is forged at a factory in Qingdao. Owner Hyun Ku Kim started business 40 years ago in his native South Korea and moved production here in 1990 to use China's cheaper labor, reports CBS News correspondent Barry Petersen. And Qingdao's port makes for easy shipping to the U.S. - except these days there's less to ship. The numbers tell the story. In a good year they'll sell 20,000 stirrups. This year they will be lucky to sell 8,000. And there was one month this past spring when they got no orders at all. Fewer orders means fewer workers; layoffs cut 500 workers down to 290. Their empty chairs litter the factory. "Before the recession, what was it like in here?" Petersen asked Kim. "This room is fully occupied," Kim said, adding that the empty chairs were a sign of reduced orders." - Steven Perez from Bookmarklet
