FIVE primary pupils experienced Singaporean culture when they joined tens of thousands of Singaporeans to celebrate their National Day during a recent prize trip to the Lion City. Watching the National Day Parade on August 9 capped the Primary Six pupils' five-day all-expenses paid trip, awarded to them by the Singapore Tourist Promotion Board. The five were selected out of 1,400 Primary Five and Six contestants from more than 800 schools for the ''Outstanding Pupils Award'', organised to encourage cultural ties between Hong Kong and Singapore. Two things left an indelible impression on the students: the patriotic and orderly spirit of the Singapore people. ''I was really touched to see 70,000 Singaporeans united in one voice singing their national anthem. I couldn't help cheering for them, and for a moment, I felt as if I had turned into a Singaporean myself!'' said Alexander Chau Kam-to of Yuen Long Government Primary School. That night, Billy Wong Chun-hang also discovered a harmony between the races living on that island. ''I was impressed to see a Malay warmly inviting a Chinese to take the vacant seat next to him,'' said the St Clement's Primary School pupil, who named Singapore his ideal country. The five had a wonderful educational experience visiting Sentosa island, the Singapore Science Centre, the Jurong Bird Park, and the Singapore National Library. They also went cycling in the East Coast Park. ''For the first time in my life I touched a live starfish and a devilfish! '' said an excited Wong King-sum, the contest champion, describing his experience at the Underwater World. But Alexander had a mishap - the devilfish (or manta ray) bit his hand and gave him an inch-long wound. Five other Singaporean pupils from Nan Hua Primary School joined them on the fourth day. La Salle Primary School's Ko Hiu-fai was stunned to find how spacious buildings in Singapore were. Nan Hua houses facilities for basketball, tennis, football, badminton, and also has a swimming pool! ''Moreover, the boys also have a fitness gym that prepares them for future military service,'' Hiu-fai added. The children also saw game animals within 50 metres at the new tourist attraction, the Night Safari at the Singapore Zoological Gardens. ''The only regret was we couldn't see the animals very clearly in the evening light,'' said Koo Jerome Leo, a pupil of St Joseph's Primary School. A crew from TVB accompanied the winners on the trip and highlights will be broadcast next Friday on TVB's Flash Fax.
