troops, then put Wang's capital Bin Prefecture () under siege. Wang fled and was killed by his own subordinates in flight. Li Maozhen and Han capitulated, sending apologies and tributes to Emperor Zhaozong. Emperor Zhaozong, who returned to Chang'an, bestowed great honors on Li Keyong and his key subordinates, but hesitated when Li Keyong proposed to attack Li Maozhen, believing that if Li Keyong destroyed Li Maozhen, the balance of power would be lost. He therefore forbade Li Keyong from attacking Li Maozhen. Li Keyong withdrew to Hedong Circuit, and, owing to his eventual defeats at the hands of Zhu Quanzhong, would not be able to return again. Flight to Hua Prefecture With Li Keyong gone from the region, Li Maozhen, who had been intimidated into an apologetic posture to the imperial court, again became arrogant. He became suspicious of Emperor Zhaozong's attempts to rebuild the imperial guards and putting them under the commands of imperial princes, including Li Sizhou, Li Jiepi () the Prince of Yan, and Emperor Zhaozong's uncle Li Zi the Prince of Tong. In summer 896, he launched an attack on Chang'an. Emperor Zhaozong immediately sought aid from Li Keyong, but with Li Keyong being unable to launch an army at that time and Li Maozhen's forces having defeated Li Sizhou's, Li Sizhou recommended fleeing to Hedong. Emperor Zhaozong initially agreed and prepared to head for Fu Prefecture (鄜州, in modern Yan'an, Shaanxi), preparing to cross the Yellow River to Hedong from there; he also sent Li Jiepi to Hedong to prepare for his arrival. However, after he left Chang'an, Han Jian sent emissaries, and then personally arrived to meet with him, to persuade him to go to Zhenguo's capital Hua Prefecture () instead, promising to do all he could to uphold imperial power. As both Emperor Zhaozong and his officials were fearful of the lengthy trek to Hedong, Emperor Zhaozong agreed and headed for Hua Prefecture instead. Once Emperor Zhaozong arrived at Hua Prefecture, however, he became effectively under Han's control, and Han stopped any real imperial attempt to engage Li Maozhen militarily. Further, he forced Emperor Zhaozong to disband the imperial guards under the imperial princes' control, and, after Li Jiepi returned from Hedong—thus exposing the fact that Li Keyong was in no shape to launch an army to aid the emperor—slaughtered 11 imperial princes. Emperor Zhaozong made peace with Li Maozhen in spring
