On 6 December 2022, a “Mini Bus Calligraphy Sign” DIY workshop was organized to bid farewell to exchange students. Handwritten mini bus sign is one of the most iconic features in Hong Kong. During the workshop, exchange students were introduced to the tradition of mini bus signs and the transformation of it from a dying trade to trendy accessories of Hong Kong. They also had the opportunity to create their own mini bus calligraphy sign. We hope that through this workshop, exchange students can bring their memories of Hong Kong back home.
