Minister of Public Security Xie Fuzhi and leading propagandist Wang Li arrived on July 16 and immediately ordered General Chen to withdraw support from the Million Heroes and instead extend it to the Workers' Headquarters. The order, relayed through Xie to a gathering of the PLA leadership in Wuhan on July 19, could not be implemented; several of Chen Zaidao's units refused to carry out the order. Moreover, a significant sub-section of the city lent support to the Million Heroes, making their position a formidable one. Generally, Million Heroes supporters saw that their being labelled a "conservative" organization would have totally tarnished their leftist credentials and lent rival groups ammunition to attack them - giving them impetus to protest the order en masse. The local PLA organization, too, felt that if they were to accede to the order, it would be an implicit admission that they had committed a grave error in the course of the Cultural Revolution - something that could be used to attack them in the future.
