It is a fairly historic and educational exhibition center. This place presents the historical buildings of the Meiji and Dazheng period and tells the history of Hokkaido's development. The prisoners in this place have excavated and built the central road connecting Xuchuan and the net. One sixth of the prisoners have different paths from their families.
