The Presidential Office was the office of the president of the ROC since 20 May 1948. It is also known as the Office of Chiang Kai-shek because Chiang was the only president who used this as the presidential office. Situated on the southeast corner of the second floor, it composed of three rooms. The middle one was served as the principal working place of the president. Inside the middle room, a huge secretaire was put sideways next to the window, with a French-made droplight above. And above the brown couch, a huge photograph of Chiang was hung on the side wall. There was an Otis elevator near the office, but Chiang Kai-shek seldom used it. Although President Chiang Kai-shek wasn't working here all the time, this office is still one of the most popular sites for the visitors in the Presidential Palace.
