Tsuen Wan is known as the "City in the Sky" because it has one of the most pedestrian bridges in Hong Kong. Whether going to work, going to class, eating, or having entertainment, the lives of Tsuen Wan residents are inseparable from the footbridge. The "Community Visiting Ambassador" of Shek Wai Kok Primary School of Yuen Yuen College of the Hong Kong Taoist Federation selected some distinctive locations along the flyover. After collecting and sorting out information, plus on-the-spot inspections and street interviews, they designed "Exploring Tsuen Wan" District” travel app allows people inside and outside the district to explore the community together.
