A Cultural Exchange Hiking Tour co-organised by Associate in English for Professional Communication and Earthfavorer was held on 26 January 2019. Nineteen HKCC students and six guests from Spain, UK, Germany, India and Kazakhstan joined the tour. Through active interaction with our friendly guests and the professional eco-guide's bilingual introduction, our students learned more about the history, culture, and ecology of the Hong Kong UNESCO Global Geopark - Sai Kung Volcanic Rock Region, Sharp Island, Jin Island (Tiu Chung Arch), Ung Kong Islands, Basalt Island, Tin Hau Temple on High Island, and Yim Tin Tsai.
