Ambassador Marcelo wrote in the guestbook: "On behalf of the government and people of the Argentine Republic, we pay tribute to the victims of the Nanjing Massacre, the people of Nanjing, and the Chinese people. May this place of memory ensure that such atrocities never happen again. Peace is an urgent priority for all nations."

On the morning of July 8, Professors Todd Salzman and Katy Salzman, a married couple from Creighton University in the United States, visited the Memorial Hall. Katy, who teaches world history, said, "Every young person should learn about the atrocities suffered by the people of Nanjing during World War II. This visit has given me a lot of strength, and I will share this experience with my students."  

Todd’s grandfather, Elmer Salzman, was a veteran of the Flying Tigers. He said, "I am very proud that my grandfather helped the Chinese people during World War II."  

On the morning of August 24, a Hungarian media delegation visited the Memorial Hall. The head of the delegation, Dániel Deme, editor-in-chief of Hungary Today, had long heard about the Nanjing Massacre and had always looked forward to visiting the Memorial Hall. He said, "During the visit, I learned about how Japan step by step invaded China. I hope China and Japan can present this period of history openly and fairly, allowing people around the world to know the truth."  

Holger, a German visitor and a medical doctor, said after his visit, "The brutality of war far exceeds imagination. Thinking about the suffering the Chinese people endured back then, my heart is filled with heaviness and sorrow."
