Guoguang Senior High School

Guoguang Senior High was founded in 1959 as a private school established by the Chinese Petroleum Corporation (CPC), Taiwan's state oil company, to educate the children of its refinery employees. In February 2005, the school was converted from private to public and placed under the affiliation of National Sun Yat-sen University, becoming the university's affiliated secondary school. Today it operates as a complete secondary school combining junior high and senior high divisions on a single six-year track, with a campus of about 6.13 hectares adjacent to Youchang Refinery Elementary School, and around 1,080 students studying under the school motto "Diligence, Respect, Sincerity, and Perseverance" (勤敬誠毅).
