HE who goes only once around the room is wiser than he who stands still, says an Estonian proverb. The advice means simply this: go travelling! But why bother, you ask. Some answers were found in the week-long ''World Trip 94'', which ended yesterday. The programme was organised by the Business Students Union of the Hong Kong University of Science and Technology (HKUST). It offered a dazzling array of images captured in photographs and postcards, a visual tour that took in the Pantheon in Athens, the Sphinx and pyramids in Egypt, the Silk Road, and the world's highest lake above sea level in Urumqi, northwestern China. But travelling is more than sightseeing said some travel experts at the opening day. ''Hong Kong people are materialistically spoiled. They need to encounter life's other side,'' said travel writer Lun Man-bill , who has travelled around three quarters of the globe. ''Seeing the adversities others face will challenge university students to see beyond a money-grabbing future and learn to develop concern for others.'' Ms Lee Lok-sze, an Antarctica explorer, suggested that students should start mapping out their own ''life travel plan'' that covers the globe by regions. The international campus of HKUST includes many overseas lecturers, one of whom is Professor Thomas Jefferson, who sees travelling as not just going places. ''It's a state of mind in how you see the world,'' said the Canadian Management lecturer.' What then is the best route to tour Europe in 60 days with HK$30,000? Second-year finance student Lawrence Yau had the answer: start from Athens in low travel season and visit the less costly, but classically picturesque southwestern European countries with a discounted Eurail pass, but skip Turkey. ''Turkey is a most exciting place, but latest information warns of civil turmoil there,'' said the winner of the Tour Route Design Competition. The programme also included two movies, The Crying Game and My Private Idaho , because ''films are microscopes of foreign cultures'', said Jacky Leung who chaired the event.
