Having travelled hundred or even thousand miles from home to arrive in Hong Kong, 60 overseas students spent 5 weeks on CityU campus to mingle with CityU EE undergraduates and some local senior secondary school students. Not only did they feel the vibrancy of this international metropolis, but also they built and programed their remote controlled airships. The hardest thing was the moment to say goodbye at the farewell and closing ceremony on 8 August 2018.
