We have recently participated in the Shanghai World Expo Axis, Baoshan GuCun Park footbridge construction. From the earliest Shanghai Yangpu Bridge, Nanpu Bridge, and now Su-Tong Bridge construction, the construction of the cable has been very mature level. In recent years, more extensive use of cable technology to the domestic and international cable-stayed bridge, a large membrane structure, pedestrian bridges, landscape bridge construction. During the 2010 World Expo, there will be nearly 10 Landscape Bridge completed. That time, the world will appreciate our country's bridge-building process, which will undoubtedly accelerate our development of cable technology.
