"University Town" refers to a special kind of city. In these cities, there are often no clear boundaries between university campuses and urban blocks. A city is a campus and a campus is a city. Universities play an important role in the city, which greatly affects the function and population composition of the city. City life also has remarkable university characteristics, and it can even be said that cities are born of universities. Typical university towns are mostly in Germany, Britain and the United States. Heidelberg, Oxford and Cambridge are famous traditional university towns. Nowadays, the concept of university town has been abused and misinterpreted. When several universities get together or a huge university is called a university town. This so-called "university town" can neither cultivate a complete urban function in a short time or unilaterally, nor has it a specific urban image. Perhaps there is only the scale of the city. A real university town should have the characteristics of a city, especially the complicated city life. An ordinary campus is by no means a city.
