Citybus, a major franchised bus operator in Hong Kong, took part in celebrating the 75th anniversary of the People's Republic of China by organizing a bus parade and exhibition. The event, held in Hong Kong's Victoria Park on 19th October, was a highlight event by the Hong Kong Special Administrative Region Government for Hong Kong's National Day. Citybus showcased several buses in the parade, including an open-top bus, a retro bus with classic livery, a hydrogen double-decker, and an electric double-decker with new design. The parade attracted over a thousand people along the streets of Hong Kong Island. In addition to the parade, an exhibition featured valuable buses from past decades, including the newly restored Leyland Olympian 178, a classic Citybus from the 1990s, and the first-ever hydrogen vehicle in Hong Kong. The exhibition allowed visitors to connect with the history of franchised buses serving Hong Kong Island and was well-received by both the elderly seeking nostalgia and younger individuals interested in bus history. Citybus expressed gratitude for the rewarding experience the event provided to participants and highlighted the importance of public transport in everyday life. They also expressed hopes for the future, aiming to have these restored buses continue to engage the public, serve as tourist attractions, and contribute to the cultural heritage of Hong Kong.
