The number of buildings and the size of barrack are small beyond my expectation, even though not all buildings have remained. Fortunately, volunteers in the museum provided a history tour, which introduced visitors the history of this island in details. The conductor took and showed us several rooms. These rooms are pretty small and just like prison, where all immigrants had to wait for long time until they were allowed to enter the United States mainland. It must have been very uncomfortable for anyone to stay in such a small room for uncountable days and nights while he or she would only have a dream, but not a promising future.
