I have been participating in the Joint School Science Exhibition Proposal since Supervising Scheme since 2020. In 2020 and 2021, I served as a judge online; in 2022, I served as adjudicator face-to-face in the Hong Kong Central Library. This year in 2023, when Hong Kong is mostly back to normal, I played a role as a supervisor to go through four brilliant projects. I believe with the advisory experience of all the teachers in the Secondary Schools and Universities, many innovative of our students could be realized.
