Guo Bo-Jia, Principle of Taichung First Senior High School (TFSHS), graduated from the Department of Mathematics in 1973. He started his educational career as a frontline teacher in Tainan Second Senior High School (TSSHS). He offered to accompany students to study on his holidays, which enhanced the performances of many students, and made donations for students with less wealthy background. His dedication and effort were recognized and he became the principle of TSSHS. “As a teacher graduating form NTNU, I’m just doing my part,” he said humbly when he became the principle of TFSHS last year.
