"Luban Lock" is a major feature of Shandong Pavilion. Luban lock is a wooden tenon-mortise structure invented by Lu craftsman Luban in the Spring and Autumn Period. It is the foundation of the traditional wooden arch in China, with Qilu flavor, closely following the theme of "Better City, Better Life" of the Shanghai World Expo.
The key point is to show the scene of Shandong city full of vitality and vigor, which greatly embodies the pioneering concept of future urban development.
