Guangxing Elementary School

Guangxing Elementary was established in 1970 by splitting off from Sanguang Elementary School, immediately taking on more than 2,000 students as Sanchong's population continued to boom. The school marked its 55th anniversary in November 2024 with a campus that has since been completely rebuilt, adding two underground levels with 304 parking spaces beneath four above-ground floors. Guangxing now runs iPad-based mobile-learning programs and dedicated English-day activities, and its new buildings were deliberately designed around a "bridge" motif — a nod to Sanchong's nickname as the "City of Seven Bridges" linking it to Taipei.

光興國小成立於民國59年（1970年），由三光國小分出設校，創校即接收兩千多名學生，反映三重人口持續暴增的態勢。學校於民國113年（2024年）11月舉辦創校55週年慶祝活動，重建後的校園設有地下兩層（可停放304輛車）及地上四層樓建築。光興目前推動iPad行動學習及英語日活動，新校舍更刻意以「橋」為設計意象，呼應三重「七橋之都」連結台北的別稱。
