刘志军
Soon after Yang departed Xiang Prefecture, though, before the army could be launched to attack Lu, Liu Zhijun the military governor of Zhongwu Circuit (忠武, headquartered in modern Weinan, Shaanxi), rebelled against Emperor Taizu and submitted to Li Maozhen the Prince of Qi. Emperor Taizu thereafter sent Yang, assisted by Liu Xun, to attack Liu Zhijun. Liu Xun quickly captured Tong Pass, and when Yang advanced to Hua Prefecture (華州, in modern Weinan as well), Liu Zhijun's subordinate Nie Shang () surrendered it to Yang. Liu Zhijun panicked, abandoned Zhongwu's capital Tong Prefecture (), and fled to Qi territory. Yang subsequently attacked the former imperial capital Chang'an, which Liu Zhijun had seized and turned control over to Qi troops; he circled around to the city's west side and fought into the city, defeating Qi troops and retaking the city. For his contributions, Emperor Taizu gave him the title of acting "Taiwei" (太尉, one of the Three Excellencies).
