Rescuers perform CPR (cardio-pulmonary resuscitation) on a "drowned" tourist on a beach during an emergency rescue drill held in Dalian city, Liaoning province, on World First Aid Day which fell on Sept 13 this year. The purpose of the drill is to teach more people first aid skills to save more lives and lower the extent of injury at the site of accidents. [Photo by Liu Debin/Asianewsphoto]
