STRIKE the right balance between studies and extra-curricular activities, and you will be ready to face society's challenges, said Dr D. S. Li, chairman of the Ning Po College school board. Dr Li was speaking at the school's recent speech day. In his report, principal K. S. Liu gave an account of the school's achievements in the past year, and outlined plans for the future. Addressing the students on a broader note, Mr Liu said it was unfortunate that materialistic interests were taking a strong hold of today's young people. Hong Kong youths were becoming superficial, caring only for appearance and image, he observed. 'They don't know what life is about. Eventually, they will become slaves to money,' Mr Liu warned. The principal praised the students for their outstanding achievement in inter-school athletics and table-tennis competitions. Giving away the prizes and certificates was K. S. Tse, Principal Education Officer (Kowloon). Fifty-two scholarships worth $171,700 were presented.
