Tainan Municipal Dacheng Junior High School

Founded in September 1946 as "Tainan Municipal Junior High School," Dacheng was the first municipal junior high school established in Tainan City, and was renamed Dacheng Junior High in 1968 as part of Taiwan's nine-year compulsory education reform. Its first campus stood on the former outer garden of the Tainan Shinto Shrine; in 1953 the school swapped land with Fengjia National School — today's Zhongyi Elementary — to reach its current site. Dacheng also has a notable institutional legacy: its 1956 branch campus later became independent as Yanping Junior High School in North District, and a separate 1960 branch grew into today's Nanning Senior High School. From 1994 to 1998 the school ran a competitive youth baseball team that, despite lasting only four years, produced nine professional players, including Tsai Ying-feng and Cheng Nai-wen.

大成國中創立於1946年（民國35年）9月，初名「臺南市立初級中學」，是臺南市第一所市立初級中學，1968年（民國57年）因應九年國教改制更名為大成國中。首個校址位於原臺南神社外苑用地，1953年（民國42年）與奉化國校（今崇義國小）交換校地，遷至現址。學校也孕育了兩所姊妹校：1956年設立的分校後獨立為北區延平國中，1960年的分校則發展成今日的南寧高中。1994年至1998年間，學校曾組建少棒隊，雖僅維持四年，卻培育出包含蔡英峰、鄭涅文在內的九位職棒選手。
