Documents and historical artifacts from the Nanjing Massacre were revealed on Monday. Collected from 14 countries, they serve as a reminder of the atrocities of history.

Military uniforms, weapons, and the daily supplies during the War of Resistance Against Japanese Aggression, and 7642 historical documents and materials were revealed in Nanjing on Monday.

"Our collections previously focused on the Nanjing Massacre, and are now expanding to the victory of the War of Resistance Against Japanese Aggression and World Anti-Fascist War. That’s why we have the evidence from the US, the UK, the Soviet Union this time," said Zhu Chengshan, head of Memorial Hall, Nanjing Massacre victims.

The evidence can be classified into three categories: historical artifacts, audio and video, and witness accounts.

One of the items is an armband that belonged to Zhou Liangchen from Ginling Women College. He had protected the local residents in the Nanking Safety Zone.

"It is the first time that we found such evidence. It shows the bravery of an ordinary Chinese to protect his compatriots. It is important to show the world how daring the Chinese people were to guard their country and people in the war," said Xu Lei, a donator.

Overseas collectors also contributed to the evidence.

"I searched these materials on Internet, and filtered and bid for them one by one from thousands of items online. It is hard work, but it is worth doing," said Lu Zhaoning, a donator.

Collection of historical evidence took the effort of nine teams in more than 60 cities, bringing remnants of history to public.
