A rigorous scientist's lifelong dream is to make China own a first-class deep-water port, and build it into the core port of Asia. He is Chang Tianqi, the commander of Yangshan Deep Water Port, the person with the primary responsibility. To build the Eastern Great Port, the project scale and technical difficulty are unprecedented in the history of China's port construction. Chang Tianqi led an elite team: marine scientist Jiang Hongyu who returned from abroad, Professor Wang Dong from a famous university, and Chen Hong, a graduate student in port studies, etc. They overcame all technical difficulties in only three and a half years.
