The Bu-Cheng-Shih-Sz Office (the Administrative Office of Taiwan) was built in 1889 in the Ching Dynasty. A newer Guest House of Imperial Envoys was later built on the side in 1892 to be the residence of visiting high officials. The main building was located behind the current location of Taipei Zhongshan Hall. During the Japanese colonial period, the arena was used for the first ceremony for the Japanese ruling and the building was used as Taiwan Governor-General’s Office for 25 years until the new office (the current Presidential Building) had been built in 1919. The building went through a dramatic relocation in 1933 when the Japanese government decided to build the Taipei Convention Center at its old location. The main part of Guest House of Imperial Envoys was moved to Taipei Botanical Garden. It became a historic monument in Taiwan and was reassigned to be under the management of Taiwan Forestry Research Institute, Council of Agriculture. Guest House of Imperial Envoys is now the only official building constructed in Min-nan style which remains to be a silent witness of the history.
