I AM concerned at your report headlined ''Teachers shocked by NCNA's Patten blast'' (Sunday Morning Post, May 2) on the New China News Agency's briefing on ''educational issues'' when the recent round of Sino-British talks entered its second day. While it is preferable that there should be early contacts with China to exchange views on educational policies, and indeed on numerous other aspects of the future SAR, let us not forget that we should be looking at two different systems in one country. Whatever problems we have with our educational system, it is very important that China should exercise self-restraint and not let its propaganda machinery run loose into the realm of education in Hongkong. At the same time, our educators have the important task of ensuring that they are not themselves ''re-educated'' and our younger generations are not taught, among other things, to shun opposing views, to call people names during exchanges of opinions or to misunderstand that being, or purporting to be, patriotic will exempt them from criminal liabilities.
