Hong Kong Customs has been playing an important role in safeguarding national security, and gave its full support to the National Security Education Day organised by the Committee for Safeguarding National Security of the Hong Kong Special Administrative Region. The department held the Hong Kong Customs College Open Day on April 18 to promote national security education to members of the public through a series of interactive activities that allowed them to learn about the department's work on safeguarding national security from multiple perspectives. Apart from the public, community dignitaries, youth groups and more than 1 000 students from 52 schools were also invited. More than 5 000 admission tickets were distributed.
