Mao, concerned that these work teams were hindering the course of the Cultural Revolution, dispatched Chen Boda, Jiang Qing, Kang Sheng, and others to join the Red Guards and combat the work teams.[1] In July 1966, Mao ordered the removal of the remaining work teams (against the wishes of Liu Shaoqi) and condemned their 'Fifty Days of White Terror'.[11][clarification needed] The Red Guards were then free to organize without the restrictions of the Party and, within a few weeks, on the encouragement of Mao's supporters, Red Guard groups had appeared in almost every school in China.[12]
