More than 800 new pieces of evidence of the Nanjing Massacre and other Japanese atrocities during WWII were shown on Thursday, two days before the 71st anniversary of the notorious war crime.

The 816 items, including documents, videos, books, calligraphy and paintings, were collected this year mainly from China, the United States and Japan, Zhu Chengshan, curator of the Memorial Hall of the Victims of the Nanjing Massacre, told a press conference.

One of the items was a record compiled by Jiang Jiaqing, who fled through Shanghai, Nanjing and Anhui Province to Hong Kong and recorded the Japanese atrocities during and after 1937.

The book records how Japanese forces conducted air raids across China. All the times and incidents in the book reflected actual events, Zhu said. "This is the first time the memorial has received such a detailed record by a refugee."
