Each era has representative projects, and those super projects have become the symbolic symbols of the era. Beijing, underground, the world's largest subway network is under construction. Shanghai Central Building, 632 meters, is the first time that Chinese people have built a building more than 600 meters. This world's tallest green building will become a new landmark of Shanghai. The Hong Kong Zhuhai Macao Bridge, the longest cross sea bridge in the world and the longest immersed tube subsea tunnel in the world, changes the future of Hong Kong, Zhuhai and Macao. The giant wind turbine at sea, the Big Mac SL5000, is the largest single wind turbine in history. Its cabin can take off and land helicopters. Super LNG ship is the most difficult civil ship to build in the world, and the most expensive cargo ship in the world. Only 13 shipyards in the world are allowed to build, and a drop of sweat will become its fatal threat. How on earth were they built? In the end, they have become symbols to show the strength of the country and highlight the style of the times of modern China.
