Listening to historical stories, practicing narrative skills, and handcrafting Zijin grass ... From August 6, Zijin grass study classes and "Zijin grass narrative messengers" summer camp were held at the Memorial Hall. During the hot summer days, the children not only gained an in-depth understanding of the history of the Nanjing Massacre, but also mastered practical interpretation skills through visits and insights sharing, and made strenuous efforts to become little messengers of history and peace.
