A homemade submarine, Sacred Dragon 2, sits in a factory in Fuyang, Anhui Province, awaiting the installation of an electronic system before its trial run. Its maker, Zhang Junlin, a retired police officer, said the ship can dive 50 meters underwater and can move at a speed of 15 kilometers per hour, carrying 12 passengers. Zhang's previous masterpiece, Sacred Dragon 1, was much smaller and underwent its maiden voyage in September 2010. Photo: CFP
