The vicissitudes of a hundred years have cast the glory of Pingkuang. Anyuan Coal Mine, the predecessor of Pingkuang Mine, was built in 1898. It is one of the top ten modern industrial mines in China, one of the origins of the workers' movement in China and one of the earliest joint-stock enterprises in China. Mao Zedong and other revolutionaries of the older generation once engaged in vigorous revolutionary activities here. In the history of China revolution and national industry, Pingkuang people wrote a brilliant stroke.
