Hong Kong police arrest 3 teens over alleged assault on 13-year-old schoolmate

Nguyen Dac Hieu, a 28-year-old international biology olympiad medalist, has decided to leave Hong Kong and become a teacher at Lam Son High School for the Gifted in Thanh Hoa Province, Vietnam. This move is part of a long-held aspiration to give back to his community by sharing the knowledge and methodologies he gained while studying abroad.

Hieu is one of over 700 teachers appointed by the province's Department of Education and Training, and he will be the only educator at Lam Son High School for the Gifted, where he will lead specialized biology classes.

Hieu's desire to return home and use his international experiences to benefit his home country was strengthened by his success at the International Biology Olympiad (IBO) and his time studying Biotechnology at the Hong Kong University of Science and Technology. He has also been involved in Vietnamese student life in Hong Kong, serving as president of the Vietnamese Students' Association in Hong Kong (VSAHK) from 2023 to 2025.

Hieu believes that many Vietnamese students, even those with academic excellence, lack opportunities to learn about international educational methods and environments. He hopes his return to Lam Son High School will help address this issue by providing early exposure to international learning methods and raising the quality of training for gifted students. The school's administration sees Hieu as a key asset in elevating the biology department and reviving the school's history of international Olympiad achievements.

Beyond the classroom, Hieu aims to inspire a passion for learning and scientific research among students throughout Thanh Hoa and the entire country.
