The Security Bureau (SB) and its disciplined services and auxiliary services held a flag-raising ceremony, a national security knowledge challenge and other activities to mark National Security Education Day today.

The SB and its disciplined services jointly held a flag-raising ceremony at the Police College this morning.

Officiating at the ceremony, Chief Secretary Chan Kwok-ki said the theme of this year’s National Security Education Day, “Proactively Align with the 15th Five-Year Plan Follow a Holistic Approach to Development and Security”, aimed to remind Hong Kong to better integrate into and serve the overall national development, and to contribute Hong Kong’s strengths and commitment to the journey of the country's modernisation.

He noted that the Hong Kong Special Administrative Region Government will spare no effort to strengthen its capability in law enforcement and co-ordination, deepen national security education, and adhere to the principle of “patriots administering Hong Kong”, so as to prevent and neutralise security risks.

Mr Chan then officiated at the Safeguarding National Security Cup awards presentation ceremony to commend the contestants of the SB, disciplined services and auxiliary services for holding sports competitions, which showcased their flexibility and team spirit to inject impetus into the promotion of safeguarding national security.

In the afternoon, the Department of Justice, the SB, the Education Bureau and the Hong Kong Shine Tak Foundation jointly organised the finals and award presentation ceremony of the Territory-wide Inter-school National Security Knowledge Challenge 2025/26.

The challenge attracted a record number of more than 132,000 students from 651 primary and secondary schools. The content of the “Hong Kong: Safeguarding China’s National Security Under the Framework of One Country, Two Systems” white paper was also incorporated into the challenge, keeping national security education abreast of the times.

In a video speech, Mr Chan thanked the principals and teachers for their support to help students gain more national security knowledge through the competitions. He noted that teachers and students of the winning school teams were invited to join a study tour to the Mainland to know the country’s latest developments and experience stability and social advancement under the safeguard of national security.

He also encouraged students, teachers and all sectors of society to proactively shoulder the duty of safeguarding national security and be the guardians of national security with a sense of responsibility and vision.

Also officiating at the ceremony, Secretary for Justice Paul Lam supplemented that since the promulgation and implementation of the Hong Kong National Security Law, order in the community has been restored, and steady economic development has been ensured. To maintain the current hard-earned situation, citizens have to safeguard national security of their own accord.

The highlights of the finals and the award presentation ceremony will be broadcast at 10.30 tonight and 7.30pm on April 19 on HOY Infotainment.

Apart from the above-mentioned activities, Secretary for Security Tang Ping-keung also attended the National Security Education Day Opening Ceremony & Seminar held by the Committee for Safeguarding National Security of the Hong Kong Special Administration Region at the Convention & Exhibition Centre.
