MORE than 100 promising Hong Kong student ambassadors will help boost the territory's image during their education overseas. As part of the annual Student Ambassador Programme, organised by the Hong Kong Tourist Association (HKTA), the students will take part in a series of activities including talks, visits to government departments, private organisations and tourist attractions prior to their departure. In addition, they will take part in charity services too. Mr James Lu, HKTA deputy executive director, said the purpose of the month-long programme was to equip the participants with as much information about Hong Kong as possible so that they could answer enquiries from their Western counterparts. As student ambassadors, they would try to impress Westerners, some of who still carry misconceptions about Hong Kong as if people here were still living in the Qing Dynasty, he added. The HKTA has organised the programme for 27 years. While addressing the young ambassadors, Professor Patrick C.P. Ho of the Department of Surgery (ophthalmology) of the Chinese University of Hong Kong, shared his 16 years of learning experience in the United States. ''After being in the US for so long, the image of Hong Kong became clearer to me as I could now look at it more objectively. The genuine characteristic of Hong Kong people only surfaces in the times of adversity. ''Most Westerners look at Hong Kong people as somehow ostentatious. But they haven't seen the real picture yet.'' The young ambassadors defeated more than 2,000 applicants to be in the programme after a tough selection procedure which included an interview and a test on Hong Kong history and current developments. Their academic achievement was also taken into consideration. Desmond Chang Tse-chun who will study in Ontario (Canada), believed that Hong Kong people were ''definitely energetic''. ''I would like to take up the responsibility (of a student ambassador) so that foreigners could see the real character of Hong Kong people through me.'' The crucial question, however, is - will these students like to come back to Hong Kong upon completion of their education - after 1997? While two of his groupmates hesitated to answer, Tse-chun said he had confidence in Hong Kong's future. ''Not only because I trust the Chinese Government, but also because there is no place like home.''
