The exhibit includes a letter written by Mao in 1924, to the late Communist Lin Boqu and KMT member Peng Sumin, both of whom had participated in the KMT's First National Congress which was held that year and marked the start of cooperation between the two parties.

Together with Mao's letter, those of a group of Chinese revolutionaries including Chen Duxiu, Li Dazhao, Hu Shi, Luo Jialun, Fu Sinian, Sun Yat-sen, Dai Jitao and Hu Hanmin will also be displayed.

The items to be shown also include a batch of magazines from 1919, including the New Youth, New Tide, Consciousness, and the Daily of the Republic of China.

Taipei sources said the exhibition are activities sponsored by the KMT to commemorate the May 4th Movement, a patriotic campaign launched in 1919 by a group of young Chinese students and intellectuals to fight imperialism and feudalism.

The movement lead to ideological emancipation and the advent of China's new culture, a turning-point in China's history.
