Tshingua, Fudan and Hong Kong City University. We also visited companies in diverse industries and met local political figures. Beijing is a city of culture and tradition.

Shanghai is an amazing city, with impressive modern constructions.
It will be interesting to see. Hong Kong is a terribly busy and modern city.
