(1) The Koxinga Era

      In the fifteenth year of the Emperor Yongli of the Ming Dynasty (the eighteenth year of the Emperor Shunzhi of the Ching Dynasty, 251 years before the establishment of the R.O.C., or 1661), Koxinga (Cheng Cheng-gong) occupied Taiwan, then he established and defined province and counties. All the southern area, including this township, was placed under the jurisdiction of Wannian County. In the sixteenth year of Yongli (the first year of the Emperor Kangxi of the Ching Dynasty or 1662), the Yangping Prefecture King, Koxinga, died of illness and was succeeded by his son, Zheng Jing, who made a change to the system. In the eighteenth year of Yongli (the third year of Kangxi, 248 years before the establishment of the R.O.C., or 1664), Wannian County was elevated to the level of state, to which this township was subordinate. At that time, the township remained to be developed and was sparsely populated, a refuge where the malefactors and bandits were holed up. With regard to the delineation of its land as well as its administrative district, all remained in obscurity.

(2) The Ching Occupation Era

      In the thirty-seventh year of the Emperor Yongli's rein in the Ming Dynasty (the twenty-second year of Emperor Kangxi, 229 years before the creation of the R.O.C., or 1683), the Ching forces invaded Taiwan, and in April of the following year (the twenty-third year of Kangxi), prefecture and counties were re-mapped. Based upon the old boundaries of Wannian State in the Koxinga era, Taiwan and Fongshan counties were set up.Located in southern Taiwan, the latter county had jurisdiction over the township. Called Renwu Villageusing its old name in the Koxinga times, the township was subordinate to Guanyinsia Neighbourhood of Fongshan Office, Fongshan County. At that time, the demarcation of the village was neither identified nor recorded in any official documents. In other words, it was merely a desolate, undeveloped small village.

(3) The Japanese Occupation Era

      In the twenty-first year of the Emperor Guanxu of the Ching Dynasty (17 years before the creation of the R.O.C. or 1895), as a consequence of the Sino-Japanese War, the Sino-Japanese Treaty of Shimonoseki was inked by ceding Taiwan to Japan. The township was subject to Fongshan Branch Office, Tainan County, and its hall was set in Kaotan, Guanyinsia Neighbourhood.
      In the twenty-fourth year of Guanxu (14 years before the established of the R.O.C. or 1898), according to the Japanese local system, Fongshan County was abolished, while the township was merged into Tainan County and subordinate to Agongdian Agency.
      In the twenty-seventh year of Guanxu (11 years before the establishment of the R.O.C. or 1901), according to the Japanese local system, the county was changed to the office. This township was put under the jurisdiction of Fongshan Office.
      In the first year of Xuantong (three years before the establishment of the R.O.C. or 1909), under the Japanese local system, Fongshan Office was abolished. This township was subordinate to Nanzihkeng Branch Office, Tainan Office.
      In the ninth year after the foundation of the R.O.C. (the ninth year of the Emperor Taisho's reign or 1920), the local system was modified by enforcing the "City, Street and Village System" in Taiwan. Kaotan District was placed under the jurisdiction of Kaohsiung Prefecture, Kaohsiung State, while its name was changed to Renwu Village. Meantime, the district chief was changed to the village chief.
      In the same year, the administrative district of the township was enlarged. It consisted of Bagualiao Village, Wukuaicuo and Dawan (the three of which had belonged to Houjin District); Sannaitan, Dashe, Linzihbian, and Houjhuangzih (the four of which had been under the jurisdiction of Nanzih District); and Baoshejia and its affiliated "dazihs" (according to the Japanese system, dazihs or xiaozihs were created under the village) such as Wucitan and Nioushihkeng. Based on this, before being separated, all the villages under the jurisdiction of Dashe Township had belonged to Renwu Village. At that time, Office (Zhuangyichang), the equivalent of the township office, was set in the Renwumingfang of Renwu Village. This was the first time that the name of the township was seen in official written records, and that the site of the office and the position of the chief were set up. As a result of this, the administrative district was settled.
      In the thirteenth year after the foundation of the R.O.C. (the thirteenth year of the Emperor Taisho's reign or 1924), due to Kaohsiung being changed to city, the township was placed under the jurisdiction of Fongshan Prefecture, but its administrative district remained unchanged.
      In the fourteenth year after the foundation of the R.O.C. (the thirteenth year of the Emperor Taisho's reign or 1925), instructed by the Japanese authorities, the Village Office (Zhuangyichang) was relocated to No. 587, Sannaitan (which currently belongs to Dashe Township), and not until the township separated from Dashe Township in 1951, did the administrative institution return to this township.

(4) From the Restoration to Now

      On August 15, 1945, Taiwan returned to the lap of the Mother Country.
      On January 15, 1946, in accordance with the regulations of the township organization of Taiwan Province, the village was changed to the township, with the township hall established, and the village chief was named supervisor instead. The township was designated Renwu Township under Kaohsiung County till now.
      On August 15, 1951, approved by the Office Civil Affairs under the provincial government, the township was separated from Dashe Township, while the site of the township relocated to Renwu Village. The Township Office was set temporarily in the original Renwu Baojia Office (the previous location of the Township Farmers' Association). At that time, to develop and prepare the Separation, there were several gentlemen rushing about to make it come true. They are Mr. Lin Chuan-lu and Lin Tsan-shou, the first and second Supervisor of the township, the former County Councilman Mr. Hsu Kun-hsiang, the former Chairman of the Township Council, Mr. Shen Shih-shun, as well as the Township Councilman Hu Tien-ssu. Thereafter, Dashe Village, Cuiebing Village, Guanyin Village, Sannai Village, Jhongli Village, and Shennong Village, all of which had belonged to Renwu Township, were placed under the jurisdiction of Dashe Township after its establishment. Therefore, the administrative district of the township was remapped and had jurisdiction over the following villages: Renwu, Wenwu (In 1950, which bifurcated from Renwu Village), Jhuhou, Bagua, Dawan, Kaotan, Wannei, and Wulin. Not until this point was the jurisdiction of the township settled. The local history is evident and traceable. For all generations to find their origin and roots, the thread has formed in an orderly and methodical manner.
      On January 1, 1954, the Township Office set in the Baojia Office relocated to a newly-built office, while the old site belonged to Township Household Registration Office.
      In 1964, with the bifurcation of Renfu Village from Wulin Village, the township had a total of nine villages under control.
      In 1983, Gaonan Village bifurcated from Bagua Village. In 1986, Houan Village bifurcated from Jhuhou Village. To have developed to this point, the township's jurisdiction consisted of 11 villages as follows: Renwu, Wenwu, Jhuhou, Kaotan, Wulin, Wannei, Bagua, Gaonan, Renfu, Dawan, and Houan.
      In 1992, because the original site of the Township Office was under reconstruction, the undertaking of the township business was transferred to the JhongJheng Hall temporarily. In 1994, the new administrative building was completed and put into commission, so the township business was undertaken in the newly-built office. In 1998, Zhonghua Village branched from jhong hua Village, Wuhe Village from Bagua Village, Chihshan Village and Renhe Village from Wannei Village, Rencih Village from Kaotan Village. By now, Renwu Township has jurisdiction over a total of 16 villages.
