Han was born in the impoverished village of Nanweiquan in Shanxi and first came to international prominence as a railway worker in Beijing. He helped set up the Beijing Workers’ Autonomous Federation (BWAF) during the Tiananmen Square protests of 1989. The BWAF was the People's Republic of China's first independent trade union, established as an alternative to the Party-controlled All-China Federation of Trade Unions.
