SEVEN students will be heading off overseas for a year of study and cross-cultural exchange. The students are Yiu Kit-yi, Tam Ka-man, Wong Sin-tak, Ng Lai-fong, Lam Pui-man, Choi Yik-sang and Tse Pui-shan. They have won the 1995-96 McDonald's AFS Scholarship and will be living with local families in Australia, Denmark, Germany, Austria, Spain and the US. 'We have been offering these cultural exchange scholarships to our crew members for nearly 10 years,' said McDonald's chairman Daniel Y. C. Ng. 'It is amazing to see the success and growth of these scholarship winners after experiencing a year of study in a culture that is different from their own'.
