BEIJING - The Central Archives was opened to more than 70 reporters from home and abroad on Tuesday, allowing them to view objects never before on public display.
One of the collection exhibited was a hand-written composition by late Chairman Mao Zedong in his boyhood.
Yang Dongquan, director of both the State Archives Administration and Central Archives, described Tuesday's event as "opening the historical door."
He said the archive had about 1.25 million volumes of files.
Also, Nanjing, capital of Jiangsu province, has a huge collection of files on the history of the Republic of China period held in the Second Historical Archives, Yang said.
He said both Chinese and foreigners can apply to access works held in the archives.
