Lexico ~ Thanks! I did some research though, and used deductive reasoning to figure out the answer. The Japanese expected a LOT of resistance in a major city like Harbin or Mukden. Therefore, they moved the capital to a smaller city - in this case Changchun. Chiang Kai Shek did the same thing in 1926 when he moved the capital of the Chinese Republic from Beijing (a major roaylist centre) to Nanjing.

I understand - MissApollo - arigatou!!!
