A deaf waitress shows picture cards to customers at a hotpot restaurant on opening in Southwest China's Chongqing municipality, May 20, 2012. About 80 percent of the restaurant's employees are handicapped, including 23 deaf waiters who provide a “silent” ordering service, which makes the restaurant as the first one of such type in Chongqing. The owner plans to open 30 public-welfare hotpot restaurants across China to supply 3,000 to 5,000 jobs to the handicapped. [Photo/Asianewsphoto]
