A live video showing how China's unmanned submersible "Hailong III" or "Sea Drogon III" was operated to dive into deep water, has inspired students to expand the horizon of knowledge on Thursday in a scientific education event in Qingdao, Shandong province.
The remote operated vehicle, carried by its mother-ship Dayang Yihao or Ocean No.1, has been executing its 52nd voyage in the southwest India Ocean.
