Baoan Temple During Japanese Colonization Period (1895-1945)
In 1895 (year 21 of Kuang-hsu reign), the Treaty of Shimoroseki was signed and Taiwan was ceded to Japan. As Tang Ching-sung fled back to Amoy,
Japanese troops attacked, captured, and brought chaos to Taipei. The explosion at Yuanshan arsenal affected Baoan Temple. In 1898 (year 24 of Kuang-hsu reign),
Baoan was taken over by the Japanese, who established the third affiliated class of the National Language School, as well as a catering trade association. Later on,
the school was renamed Dalongdong Public School. Years after the take-over, Baoan Temple was so poorly maintained that the structure and the paint were coming apart.
Leaders in the three townships therefore initiated the fund-raising for reconstruction.
Reconstruction and Rite of Completion
Years 1917-1919 (years 6-8 of Taisho reign) saw one major reconstruction of Baoan Temple. Fund-raising leaders included: Shen Chu, Chen Pei-ken, Lin Ming-te,
Li Sheng-yuan, Cheng Ken-mu, Chen Chun-hui, Huang Tsan-chun, Lin Ching-tun, and Tsai Shou-san. The project lasted two years. To celebrate the successful
completion of the biggest renovation to date, temple management planned five-day-long festivities, which started on January 18 (28th day of the 11th moon in year
8 of Taisho reign), 1920 (year 9 of Taisho reign).

Service altars were set up as follows: The Jade Emperor altar was in the front of Baoan Temple, Master Chang’s altar in the front hall of Baoan, North Pole temple
at Koo Hsien-jung’s villa, Five Grains altar in the front of the new Matsu Temple at Dadaocheng, and Dragon King altar at the new store to the east front of Baoan.
There were four smaller altars: Outer City God altar was at Taiping Street, Fu-de altar was inside Daojiang market, Guanyin altar was on the side of City God temple,
and Kitchen God altar was inside Fu-de Shrine at Niu moche village. Elsewhere, other individuals also volunteered other altars.

The expenses for the five-day festivities totaled about half a million dollars. The fact that Baoan Temple was able to raise such a large amount within a month or two
and invite so many political and local notables shows how resourceful and influential Baoan was at the time.
