張角
Zhang Jue used a form of Taoism to cure the sick by confession of sins and by faith healing. The religion and the politics of the Zhang brothers were based on belief in an apocalyptic change in the order of the world. They told their followers that in the "jiazi" year, the beginning of the new sexagenary cycle, the sky would become yellow, and that under this new heaven the rule of the Han dynasty would end and a new era of government begin. The characters "jiazi" became a symbol of the coming change and, later, when the followers of Zhang Jue went to battle they wore a yellow cloth bound about their heads as a badge. From this came the term Yellow Turbans.
