When speaking of the Nanjing Massacre and the World Anti-Fascist War, Iris Chang's mother Ying-Ying Chang expressed her deep concern that this painful chapter will be forgotten. She said that it is necessary to preserve and share this history through literature, media, and art. "We must show the next generation the cruelty of war, so that they can understand how precious peace is. If we fail to do this, the memory will fade completely within a few generations, history is certain to repeat itself," Ms Chang warned.
