In 1947, China's political situation changed again. Government administrators' families who had lived in mainland China came to Taiwan, and the government let their children to study at He-ping High School. 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. On August 1, 1947, He-ping High School became "The Affiliated Senior High School of Taiwan Provincial Teachers' College." There was also a junior high school section. In October 1949, the school took in 310 students from the National Revolutionary Army's Children's School, the largest number taken by a school in that area.
