Thanks to the hard work of the PolyU community over the years, PolyU has grown as one of the top 100 universities in the world, making remarkable contributions to society through world-class education and research and the nurturing of talents in different fields. In celebration of the University’s 85th Anniversary, we are honoured to have invited PolyU University Fellow and Artist-in-Residence Dr Liza Wang to interview five former Council Chairmen and former Presidents of PolyU, revealing the ‘secrets’ related to the University’s development during their time.
