Yesterday I told you guys that China is now renowned as an "infrastructure monster", having accomplished numerous engineering miracles with incredible speed.  Needless to say, it takes sophisticated mechanical devices to get all of those jobs done.  Following is a vivid report on the story of Zhenhua(ZPMC), a Chinas heavy mechanical company who specializes shipbuilding and the construction of bridges over seas.

P.S.  You may say the gigantic crane is not a cutting-edge technology solely patented by China; many countries can make it, and they just prefer rent it from China to produce it by themselves in accordance to comparative interest.  You may be right, but please note China has ambition to be the number one in every field of industrial products, and heavy mechanical device is just one of them.
