What kind of role should it be? What were the different opinions? How was the project demonstrated? What was the conclusion of demonstration? Those are the issues that many people care and don't know about.To memorize the realization of the century dream of Chinese people and to record the history of development of TGP,the author presents a compendious introduction to the project.展开更多
