DEAD schoolboy Eddie Wong was a well-behaved and hard-working pupil, according to his principal and teachers. The 10-year-old Primary Five afternoon class student was so gentle and well-behaved that he had won best conduct prizes at school, said the principal of the Buddhist Wong Cheung Um Primary School in So Kon Po, Chiu Tze-cheung. He said Eddie had been at the school since Primary One and was a good student. Mr Chiu said: 'He was among the three shortest students in his class. He was slim too. Although he was at Primary Five, he looked like a Primary One student. 'He was quiet and shy and not talkative in class. He studied very hard and attended remedial classes. His academic performance was of average standard.' The headmaster said Eddie was going to attend Chinese remedial class on Monday before he disappeared. Remedial classes begin at 12.30 pm and usually last for 30 minutes before the normal class begins at 1 pm. The boy arrived at the school at about 12.15 pm on Monday by private school light bus. Mr Chiu said the bus was organised by parents and did not belong to the school. Students getting off the bus entered the school themselves. But he said the school would step up security following the tragedy. 'Two staff members will be deployed at the entrance of the school at noon to keep an eye on pupils and make sure those getting off the bus go into school immediately,' he said. He said he would tell students about the incident and warn them not to follow strangers. Eddie's classmates had been told by teachers that Eddie was absent from school because he was ill, after police asked them to keep the case confidential during investigations. 'Now we will tell students the truth. We know students may feel frightened. We will give them counselling, especially Eddie's classmates. 'We think not only students, but also teachers need counselling,' he said. The boy had also attended tutorial classes in a youth centre next to his school in 1992 and 1993 when he was in Primary Two and Three. The centre's supervisor, Leung Pui-hung, yesterday recalled that Eddie was diligent and came to the centre almost every weekday from 9 am to 11 am. He then had lunch at the centre before going to school. 'I guess his family is quite rich. His father is a businessman and every time he was driven to the centre by a sedan car,' said Ms Leung. 'But he never showed off. He was very polite and greeted his tutors and other staff in the centre. He followed teachers' instructions.' Ms Leung said Eddie was not active but sometimes joined picnics and interest classes for painting and making handicrafts. 'He later quit our classes because his mother said he was exhausted. I believe his health was not very good. He looked rather weak,' she added. Principal Chiu said Eddie had two older sisters. The child was the only boy and the youngest in the family. Police yesterday went to the school to retrieve Eddie's school bag, which had been left there on Monday.
