YUEN Long Government Primary School's Chau Ka-yee was on an aircraft just as it came in to land in Singapore. ''As I peeked through the window of the plane, I saw a country covered with lush greenery and I realised why Singapore is known as the Garden City. It was really amazing,'' said Ka-yee, the second prize winner of the Outstanding Pupils Award. After beating more than 1,200 Primary 5 and 6 pupils in the competition in July, Ka-yee and four other winners won an all-expenses paid four-day trip to the island republic recently. Besides visiting famous sights such as Haw Par Villa, the Zoological Gardens and Sentosa Island, they got to understand better the country's educational and transportation systems. ''Studying in Hong Kong has less pressure than in Singapore because they have to face open exams from Primary 3. However, I still prefer their system because every student is given a chance to go to university if they are willing to spend two more years of hard work,'' the 12-year-old Ka-yee said. According to Ka-yee, Primary 3 pupils in Singapore have to take an open exam to determine whether they can enter the four elite schools. Less outstanding pupils would go to other schools, where they would be given proper training according to their standards. She also appreciated the country's transportation system. ''During rush hour, only cars with permits can enter certain busy area. Besides, the Government limits the number of cars, which helps to avoid traffic congestion,'' she said. Li Ka-ho, the winner of the award, said he was stunned by the prosperity and cleanliness of the country. For the 12-year-old, Singapore is an impeccable country. ''Before the trip, I thought Singapore was not that great a city, but now, I think it's better than Hong Kong. There are a lot of skyscrapers and big department stores. ''Singaporeans are very energetic and they always put on a smile. If there is a chance, I would love to emigrate to the country,'' said Ka-ho, who is however emigrating to Canada next year. Although Singapore is known as a ''fine'' city, Ka-ho said the legislations were reasonable. and the rules were for the good of the people. The now Form 1 student said he was very disappointed when they were unable to take a subway ride, because an accident had disocuraged them.
