The Sixth All-China Labour Congress was held in Harbin from August 1 to 22, 1948. It called upon the working class all over the country to unite closely with the rest of the people and give vigorous support to the People's Liberation Army, so as to rapidly accomplish the historical task of overthrowing the reactionary Kuomintang rule and establishing a new China. It adopted the ``Resolution on the Current Task of China's Labour Movement'' and decided to re-establish the All-China Federation of Trade Unions, the unified national organization of the Chinese working class. The previous five All-China Labour Congresses had been held in 1922, 1925, 1926, 1927 and 1929. On April 30, 1953, the Third Plenary Session of the Sixth Executive Committee of the All-China Federation of Trade Unions resolved to change the title of the then forthcoming Seventh All-China Labour Congress to ``the Seventh National Congress of Chinese Trade Unions''.
