The "Changing Dragon City-Kowloon City Theme Walking Trail" is approximately 6.5 kilometers long and is divided into five characteristic sections. The north side starts from Kowloon City Walled City Park to the south of the Church of Our Lady of Hung Hom and is divided into five sections with five themes. The Urban Renewal Fund appointed the Hong Kong Sheng Kung Hui Welfare Association Limited in September 2017 to implement this project. The entire walking trail project was launched in January 2018 until December 2023 for a period of 6 years.
