Zhang Wuyi tests his newly developed civil submarine Tuesday in Wuhan. Zhang is a laid-off worker who came up with the idea of making a submarine five years ago. After numerous failures, his civil submarine was successfully launched in 2012. Later, he transformed his submarine from an unmanned underwater fishing device to one with remote control and camera for picking up image underwater. (Gao Yinan)
