Several subjects and teams (e.g. Civic and National Education Team, the Library, Citizenship and Social Development, and Life and Society) have co-organised a book exhibition on “National Security Law” and “Basic Law” and a cross-curricular event titled “Learning ‘National Security Law’ and ‘Basic Law’ from Books”. The aims of the activities were to promote pertinent legal knowledge to students. Several “Students Ambassadors” who are responsible for promoting the “Basic Law” have actively participated in the event. The students have assisted teachers and schoolmates on event promotion and participation. A number of students were awarded prizes in the event.
