To mark the 29th anniversary of the establishment of the Hong Kong Special Administrative Region and the 6th anniversary of the National Security Law’s promulgation and implementation, the Police Force’s National Security Department (NSD) organized a promotional “National Security Express” bus tour across the city.
As part of the month-long publicity campaign, five Kowloon Motor Bus (KMB) double-deckers were adorned with National Security-themed decals and sent around Hong Kong to spread the message that everyday lives are closely related to national security.
From July 1 to 28, the “NS Express” ran on four routes — 6, 271, 7, and 171 — covering Hong Kong Island, Kowloon, and the New Territories. The routes themselves were chosen specifically, coming together to form 6271 7171 — the hotline used for reporting to the NSD via SMS.
To encourage public participation, the NSD also launched a social media campaign inviting citizens to submit photos they had taken of the themed buses to a designated post on the Hong Kong Police’s Facebook page, using the hashtags “#NationalSecurity” and “#HKNSL”. The first 100 participants each day will receive a limited-edition souvenir.



On June 30, the Force held a launch ceremony for the promotional campaign at the KMB Kowloon Bay Depot, officiated by Director of National Security Kelvin Kong Hok-lai and Assistant Commissioner of Police (National Security) Kenneth Kwok Ka-chuen. Students who had received awards in the “NStudio Marketing Proposal Competition” were also invited to attend.




The students were taken on a tour of the bus depot to learn about the bus company’s daily operations and various smart management systems, helping them understand the vital role public transport plays in safeguarding national security.
Kwok hoped that the campaign would encourage a sense of national security and raise awareness of the NSD hotline.
He further emphasized the importance of a holistic approach to national security, noting that public transport services support societal security by providing safe and reliable transport networks, and resource security by utilizing eco-friendly technology such as solar power and electric vehicles.
The publicity campaign left students with a deeper, more practical understanding of national security. After observing the recycling of bus tires and car-washing water at the KMB depot, Form Three student Leung remarked that she now understood how deeply resource security is woven into everyday life.

Form Four students Kong and Chan added that the campaign illustrated how the National Security Law has helped to gradually stabilize Hong Kong’s political climate, giving them a clearer sense of why safeguarding national security matters.
