My science is architecture. Compared with urban design, architecture is a more professional discipline, while urban design is a more comprehensive discipline, which will cover the content of architecture, as well as planning, landscape and even operation and policy. I personally have a strong interest in urban architecture and urban space design, which is why I choose to continue to study urban design. I studied in exchange at Munich University of Technology and also studied urban design in GSD. I found that the urban design in Germany is quite different from that in the United States. In Germany, the literal translation of urban design (Städtebau) is "urban architecture", which also shows that urban design in the context of German culture pays more attention to the influence of urban texture and the shaping of architectural space on the behavior of citizens, and discusses how to create a more harmonious and sophisticated space atmosphere. In the United States, urban design (Urban Design) is more like a pan-dimensional system discussion, the design as a perspective, to think and deal with the city's problems. In many cases, in addition to physical space, policy and operational issues are also discussed. Sometimes, for urban design, European culture likes to say Small is Beautiful, pursuing exquisite urban space, elegant urban experience and comfortable urban environment. American culture prefers to say Make No Little Plans, pursuing the overall effect, the balance of all parties and the development of the system.
