Outside the bookstore and museum, I am going to do a super engineering series. I don't know if it can be done. The Donghai Bridge is a sea-crossing bridge connecting Shanghai Lingang and Yangshan Deep Water Port. The full length is 32.5 kilometers ., of which the sea-crossing part is 25 kilometers. Driving through the East China Sea Bridge, I will unconsciously lament the great creation of mankind. On the vast sea, not only has Haiyan, but also this long dragon stretching for more than 20 kilometers. And now the East China Sea Bridge is not lonely, on both sides of the bridge, the East China Sea Bridge offshore wind farm, this is a great innovation, is a model to make full use of wind energy.
