Since 2005, the United Nations Educational, Scientific and Cultural Organization has designated 27 October as World Day for Audiovisual Heritage. To echo this, film archives around the world organise various activities every year. This year, the Hong Kong Film Archive specially designs an audiovisual teaching kit to further promote the importance of audiovisual heritage. By watching videos of talks given out by young KOLs and finishing the worksheet, students will be able to understand the historical and cultural significance of audiovisual heritage.
