Mudan Elementary School

Mudan Elementary was proposed in 1940 and opened in 1941 as a branch classroom known as Wudankeng Field School, during the Japanese colonial era. Named for Mudan ("peony"), a small settlement along the Mudan (Wudankeng) valley near Shuangxi's rail line, the school reflects the area's sparse, mountainous mining-era geography. Today it is classified an official "remote" (偏遠) school, with only about 30 students.

牡丹國小於昭和15年（1940年）提出設校計畫，昭和16年（1941年）以「武丹坑分教場」之名開辦，時值日治時期。校名「牡丹」取自雙溪鐵路沿線的牡丹（武丹坑）谷地小聚落，呈現出當地稀疏、多山的礦業時代地貌。學校目前被列為正式「偏遠」地區學校，全校僅約30名學生。
