Li Hanzhi
Shortly afterwards, when many of Li Keyong's subordinates suggested that he should head to Chang'an to pay homage to the emperor, Gai argued against it, pointing out that this would cause the people of Chang'an to be disturbed, as they would not be able to discern Li Keyong's intentions. Li Keyong agreed, and withdrew back to Hedong Circuit. Meanwhile, when Li Keyong's general Li Hanzhi requested the military governorship of Jingnan, but Li Keyong declined on the basis that the imperial government had already commissioned Su Wenjian (), Li Hanzhi complained to Gai. Gai, fearful that Li Hanzhi would eventually rebel, tried several times to speak on his behalf with Li Keyong, but Li Keyong refused to grant Li Hanzhi a military governorship, believing that doing so would hasten Li Hanzhi's betrayal. (Li Hanzhi did, as Gai feared, seize Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi) in 898, turn against Li Keyong, and submit to Zhu Quanzhong.
