The “East District” was transformed from Jhuwei and Dongmen in the Japanese Colonial Period. In 1946, Anshunjhuang (called “Annan” for the time being) was included in this City and, therefore, made this District extend to the southeastern part of Tainan City and this District still keeps its original name “East District”. In the early days after the Second World War, most of this District was full of farms, and then National Cheng Kung University was founded, Jhugaocuo and Huweiliao were redistributed as the industrial park, and the 4th readjusted region occupied an area of 304 hectares as developed in Jhugaocuo in 1977. Accordingly, East District became an idealistic cultural and educational residential district because it was equipped with well-founded facilities and a drastic increase in population. In 1981, the District governed 42 villages in total. In May 1994, Chongshan Village was divided into Chongshan and Chongcheng, Dajhih Village divided into Dajhih and Dongjhih, and Guansheng Village divided into Guansheng and Dongsheng. Upon the adjustment on February 4, 2002, the District governed 45 villages in total covering 1,207 neighborhoods. Upon the readjustment on January 9, 2006, Guansheng Village was divided into Guansheng, Wensheng and Nansheng. For the time being, the District governs 47 villages in total covering 1,279 neighborhoods. On July 27, 2010, owing to Chunghsing Village and Fuguo Village being incorporated in Houjia Village, this District governed 45 villages, covering 1240 alleys. On December 25, Tainan County and Tainan City combined into a single city, but the District still kept its name. On January 29 2018, villages and neighborhoods were adjusted, and the District governs 45 villages covering 877 neighborhoods in result.
