Su Tseng-chang
After the successful conclusion of the 2004 election, Chiou was moved back to the National Security Council as Secretary General, and remained there until early 2007, when he was moved back to the Presidential Office as Secretary General. On May 17, 2007, along with the rest of the Cabinet of out-going Premier Su Tseng-chang, Dr. Tsai Ing-wen resigned to make way for incoming Premier Chang Chun-hsiung and his Cabinet. Premier Chang named Chiou I-jen, to replace Dr. Tsai as Vice Premier.
