Bai rose to fame during the warlord era by allying with Huang Shaohong (a fellow deputy commander of the Model Battalion of the Guangxi First Division) and Li Tsung-jen as supporters of Kuomintang leader Sun Yat-sen. This alliance, called the New Guangxi Clique, proceeded to move against Guangxi warlord Lu Rongting in 1924. The coalition's efforts brought Guangxi Province under ROC jurisdiction, and Pai and Li represented a new generation of Guangxi leaders.
