[4] Around the new year 892, he submitted to Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan), who was then engaged in a lengthy campaign against Shi.
[5] (Ganhua's capital Xu Prefecture (徐州) would eventually fall to Zhu's army in 893, and Shi committed suicide.
[4] In 901, the powerful eunuchs, led by Han Quanhui, feared that then-reigning Emperor Zhaozong and the chancellor Cui Yin were about to slaughter them.
They therefore seized Emperor Zhaozong and took him from the capital Chang'an to Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi), then ruled by the eunuchs' ally Li Maozhen.
As of fall 902, with his army facing rains and the accompanying illnesses, Zhu was considering lifting the siege and withdrawing to Hezhong (河中, in modern Yuncheng, Shanxi).
Liu first attacked Baoda, capturing Liu Yanhui (劉彥暉) the prefect of Baoda's Fang Prefecture (坊州, in modern Yan'an), and then defeated Li Jihui at Meiyuan (美原, in modern Weinan), forcing Li Jihui to withdraw back to Jingnan's capital Bin Prefecture (邠州).
Liu was rewarded with the honorary chancellor designation of Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事), while Kang was made the military governor of Baoda.
Still, in spring 908, with the Liang commander Li Si'an (李思安) unable to capture Lu Prefecture, Emperor Taizu went to the frontline himself to oversee the siege, while also summoning Liu from Kuangguo (which, shortly after, Emperor Taizu renamed Zhongwu (忠武), swapping the name with the circuit headquartered in modern Xuchang, Henan) to command the forces involved in the Lu operation.
Liu had initial successes against Jin forces and requested to stay to finish the siege, but Emperor Taizu was concerned that Qi forces might attack Zhongwu, so he had Liu head over to Jin Prefecture (晉州, in modern Linfen, Shanxi) to stay there and gradually return to Zhongwu.
[11] Shortly after, the Qi military governor of Baosai, Hu Jingzhang (胡敬璋), attacked Shangping Pass (上平關, in modern Lüliang, Shanxi), but was repelled by Liu.
Liu believed that it would be difficult to do so, so he declined by stating that his food supplies were not sufficient, so Emperor Taizu let him return to Zhongwu.
[12] In late 909, Li Maozhen wanted to capture Shuofang Circuit (朔方, headquartered in modern Yinchuan, Ningxia) to accommodate Liu Zhijun.
When Shuofang's military governor Han Xun (韓遜) sought aid from Later Liang, Emperor Taizu sent Kang Huaizhen and Kou Yanqing (寇彥卿) to attack Jingnan Circuit to force Liu to withdraw.
Kang and Kou quickly captured Nin (寧州), Yan (衍州), and Qing (慶州, all in modern Qingyang, Gansu) Prefectures.
In response, Emperor Taizu also ordered Kang and Kou to withdraw, and, anticipating an attack by Liu against them, sent aid forces to Qing Valley (青谷, in modern Xianyang).
Subsequently, at Li Jichong's invitation, Liu relocated his family to Tianxiong's capital Qin Prefecture (秦州).
Liu, hearing the news, ended the siege of Bin Prefecture and returned to Fengxiang, but grew increasingly fearful, so he took 70 soldiers close to him and fled to Former Shu.
[14] Wang Jian initially welcomed Liu Zhijun warmly and made him the military governor of Wuxin Circuit (武信, headquartered in modern Suining, Sichuan).
[4] In 916, Liu served under Wang Zongbo, who was commanding one of the two prongs of the Former Shu attack against Qi and subsequently participated in a siege of Fengxiang Municipality.
[1] Further, it was said that those jealous of Liu were spreading a false prophecy stating, "Once the black bull gets out of its encirclement, the brown rope will be broken."
(That false prophecy was written in that way because Liu had dark skin color and was born in a Chou (丑) year (i.e., year of the Ox); and Wang's sons/adoptive sons used the generational character Zong (宗), which was a homophone of "brown" (棕), while his grandsons used the generational character Cheng (承), which rhymed with (or perhaps was a homophone of, at that time in history) "rope" (繩, sheng).
