On the morning of May 28, Long Zilan, a student from Pui Ching Middle School, Macau, visited the Memorial Hall. Fourteen-year-old Long Zilan is a new generation singer of “The Song of Seven Sons”. At the MourningSquare, the visiting delegation paid a silent tribute and laid flowers to the victims of the Nanjing Massacre. Later, they visited the Exhibition of Historical Facts on the Nanjing Massacre.

"Do you know 'MACAU' isn't my real name? I have been away from you so long, mother..." At the end of the historical exhibition hall, Long Zilan sang “The Song of Seven Sons” to the accompaniment of piano. The beautiful melody and deep feeling made people moved.

At the event themed "Inheriting Memory and Cherishing Peace", Long wrote "I love China. I am a child of China" on a Zijin Grass sticker and put it on a “dove” display board.

Director Zhou Feng sent the book THE RAPE OF NANKING：The Forgotten Holocaust of World War II by Chinese-American writer Iris Chang to Long. "Iris Chang was the first female writer to reveal the historical truth of the Nanjing Massacre to the Western society," he told Long. "I hope you can have a deeper understanding of the history by reading this book."
