Quanzhou Luoyang Bridge is China's first cross-sea Dashi Bridge. It was built in 1053 and it took six years to complete. The stone bridge is 1,200 meters long and 5 meters wide. There are 44 piers and there are handrails on both sides of the bridge. After thousands of years of wind and rain, there are only 31 bridge piers left in Shiqiao, which is 1188 meters long. At the time of the bridge, the craftsmen thought of using the specialty of Quanzhou, the oyster. Oysters are characterized by two shells, one shell attached to the rock or another oyster, which are joined together, and the other shell is covered with its own software. Moreover, the oysters have a strong ability to reproduce, and they are not perforated. Once they are glued with the stone, they can not be shoveled with a shovel. Craftsmen facilitate the use of this characteristic of oysters to consolidate the bridge base. In a few years, the oysters connected scattered stones and stones into a whole. Luoyang Bridge has not been scattered for thousands of years. It can be said that oysters have played a huge role, of course, because of the wisdom of artisans. This design is a major innovation in the history of architecture.
