有人说到中国看５０００年去西安，看１００年去上海。位于东南沿海的上海和位于西部腹地的西安，是两个反差很大的城市，一个代表光韵渐逝的古代文明，一个代表翻天覆地的现代中国。两个城市，两种风格，迥异的城貌中蕴含着冲撞，细微的差别里预示着演变，这是转型的中国龙的两头，这是可见的过去，现在和未来…… Some people say that China is going to Xi’an in 5000 years and Shanghai in 100 years. Located in the southeast coast of Shanghai and Xi’an in the western hinterland, there are two big contrasting cities, an ancient civilization representing the passing away of light and a modern China representing earth-shaking changes. The collision between the two cities, the two styles, and the distinctive urban landscape implies that the subtle differences indicate the evolution. This is both ends of the transformation of the Chinese dragon, which is a visible past, present and future.
