HSNU was founded in Taiwan as "Taipei Third State High School" in 1937 under Japanese rule.

At that time, Taiwan Provincial Teachers' College (now National Taiwan Normal University) was preparing to establish an experimental high school as a teachers' training ground, so the college applied for the establishment of a new school.

However, it was not until an associate professor of the NTNU's Education Department, Huang Zhen-Qiu, became HSNU's principal, were the high school and the university closely tied.

The annual graduation ceremony is an event organized and decorated solely by students that have been admitted into university.

The team of students adorn the settings of ceremony to a theme, arrange the entertainment programs and shoot their own music videos.

The girls' uniform consisted of a white button-down shirt and a light blue suit skirt (with double folds down the front).
