In early days, Han people in southwestern Taiwan called villages zhuang. Villages of aborigine people were called she. Names of the places ending with she might former residence of aborigine people.
Dashezhuang (between Zhongjunguo and Bengxianguo) in the west of Guangyingshan used to be place where A ka of Siraiya Tribe lived. Failing in fighting against the Netherlanders, some people moved to Suozaigang in the south of Dapengwang, Donggang Districtship, Pintung County. Most of them still remained where they were under rule by the Netherlanders.

In Koxinga period, Pingpu in A la were pushed aside from where they lived by Han people. People still called the place Dashe.
To solve food shortage in Koxinga period, soldier-farmer policy was fully adopted. Soon, batiaotuntian instruction order was given. Dashe District was in Guangyingshan cultivation area. At late Qing Dynasty, the names and range of the place changed under different emperors. The names changed as Guangyingshanzhuang→Guangyingli→Guangyingzhongli; the range was Guangyingshanzhuang covering Guangyingshangli, zhongli, xiali, neili, banpinli and xinlongwai, neili in late Qing Dynasty (currently Yanchao District, Dashu District, Dashe District, and Renwu District in Kaohsiung County; Nanzi, Zuoying, Gushan and Yancheng Districts in Kaohsiung City).
During Japanese occupation, range differed as Guangyingzhongli→Nanzikeng Branch Hall→Renwuzhuang Sannaitan. In earlier days, Renwuzhuang was in different administration areas. Politically, it was in two local fractions: sannaitan represented village in Guangyingzhongli; Renwu covered Guangyingxiali and banpinli.
After reorganization, they were under the name Renwuzhuang. The zhuang office (District address) was still at 587 fandi, sannaitan, the old address of Dashe District Office.
Under control of the Japanese, the two fractions got along well. After the Restoration, self-government was adopted. Renwuzhuang was reorganized as Renwu District. Renwuzhuang was in disadvantageous situation and there were often conflicts. At the end of 1949 after promulgation of Regulations Governing Division of Local Self-government of Cities and Counties in Taiwan Province, with rich resources, people in Renwu fought for the separation of District. In the 2nd conference by Kaohsiung County Council on 29 May 1951, Renwu District was divided into Districts—Dashe District and Renwu District.
People in Dashe District had been arguing about the name of the District. Those focusing on local culture believed that sannaitan was the village with most people and the center of politics, economy, culture and traffic. The District office was also there. Therefore, the name should be Sannaitan. Those with new ideas believed sannaitan was not easy to read and sannai was not good. The police station and elementary school were named Dashe. The name Dashe would be better and sounded better. No one mentioned the name Guangyingshan, the earliest name. Finally, most people voted for Dashe.
On 15 August 1951, under approval of Civil Affairs Bureau, Taiwan Provincial Government, Dash District was finalized to be separated from Renwu District. The range was current District border. The District office then was on current Sanmin Road. Dashe District has 9 villages—Dashe, Shennong, Guangying, Cuipin, Zhongli, Sannai, Baoshe, Jiacheng, and Baoan. Total area is 28.23 square meters.
Most people in Dashe District speak Minnan and some speak Hakka. This is a District emphasizing agriculture, industry and commerce. The most famous produce includes dates and guavas. This is also the largest milk junket area in Kaohsiung County. Output of milk is highest in Kaohsiung County. Guangyingshan is a famous scenic spot in southern Taiwan. Factories in Dashe Industrial Park have created job opportunities. National Highway #2, I-Shou University, Shu-Te University and E-Da Hospital have brought tens of thousands of consumers to Dashe District. The old commercial center in Sanjiaoyong in old village has been replaced by Zhongshan Road outside Guangyingshan. Humanitarian ecology was booming and diverse. With local development, Dashe District has become a good place for industry, commerce, agriculture and sightseeing.
