The Great War that changed the world order is revisited through exhibits like news publications, postcards, fund-raising posters, commemorative medals and guns from the war period, along with valuable historical photos and film footage. The exhibition also reveals the far-reaching impact the war had on modern China and Hong Kong at the political, military and social levels. In commemoration of the centenary of the end of the First World War this year, let us reflect on the heavy price paid for war, and appreciate the value of world peace.
