This work focuses on the operation of public transport and cities and showcases the inseparable nature of Fengyuan train station interchange and urban development. It takes the city in which people live and, through elevated disks that rotate and overlap, transforms images from along the mountain line connecting Fengyuan, Tanzi, Daya, Shengang, Houli. Dongshi, Shigang, Xinshe and Heping districts into cross-sections of city life. In this way, those passing through the interchange see shifting, replacing, overlapping, disassociated, cyclical city scenes depicting the future development, operation and exchanges of the city.
