The Nanjing Massacre Memorial Hall has collected more historical documents that shed light on the murder of hundreds of thousands of people in the city during the Japanese invasion to China.

Drawing back one of the darkest chapters of China's modern history, this latest collection of over 400 articles includes pictures, letters and videos. They came from both domestic and overseas collectors, and most will be available to the public for the first time. A letter written in 1937 by a Japanese soldier, records the Japanese troops' occupation of Nanjing and the orgy of killing that followed.

Zhu Chengshan, curator of Nanjing Massacre Memorial Hall, said: "More than 60 years ago, these articles witnessed the massacre that happened in Nanjing. They've now come out to prove history. They are very valuable in countering Japan's denial of reality and its distortion of history. "

The memorial hall is located on one of the sites where 300,000 Chinese prisoners of war and civilians were killed by the Japanese invaders in 1937.

With a budget of 540 million yuan, the Memorial Hall has launched an expansion project to renovate older sections and add new display areas. The materials collected will be shown when the new exhibition rooms open.
