Nanhu Settlement was a star of Nanjing City in 1980s, called the "burgeoning town". But it has been declined for a long time until the early or 2000. The government or Jtanye District has made a series or space reforms for this settlement since 20m by now, which or these full or success and failure. But the reforms of the 10 years bring some negative effects, whose reason is not out or the design, but the collective memory or people lived there. Throughout the analysis or these forgotten people and their place, we will rind that it is their collective memory evoke the space resistance which makes the space reforms cannot get the expected effort smoothly. The settlement is not only where they live, but also their whole world.
