It is one of the most hotly debated topics in town: does national education need to be on children's school curriculum - and if it is, what should it teach them? But it seems those who decide the final shape of Hong Kong's education policy do not have an opinion. At least, not one they want to share. In a poll of top officials relating to the issue of national education, the Boys' and Girls' Clubs Association of Hong Kong asked Chief Executive Donald Tsang Yam-kuen 'why the mainland must be ruled by the Communist Party instead of letting different parties take turns to rule?' Tsang's reply was simple - see the central government's website. 'Please browse the following website for China's political system and constitution,' a letter in response read. The questions to top officials were part of an association survey into what youngsters expect to learn from a national education subject. The questions were raised by students who took part in a focus group. Chief Secretary and chief executive hopeful Henry Tang Ying-yen's reply said he could not provide an answer as the question was related to the mainland's electoral system. Secretary for Education Michael Suen Ming-yeung did not reply to the question of whether mainland textbooks should make reference to the June 4 Tiananmen Square crackdown. More than 200 pupils in Form Four and above took part in the study in July and August. Sixty per cent opposed the idea of a national education subject. A four-month consultation on the proposal ended yesterday and the Education Bureau said it received more than 1,000 submissions.
