In 1927, following the collapse of the First United Front, Kuomintang authorities ordered Zhu to lead a force against Zhou Enlai and Liu Bocheng's Nanchang Uprising. Having helped orchestrate the uprising, Zhu and his army defected from the Kuomintang. The uprising failed to gather support, however, and Zhu was forced to flee Nanchang with his army. Under the false name of Wang Kai, Zhu managed to find shelter for his remaining forces by joining warlord Fan Shisheng.
