In 195, Emperor Xian, who had been a puppet emperor under the control of the generals Li Jue and Guo Si since 192, managed to escape from their clutches in Chang'an, the imperial capital, and return to the old capital, Luoyang. Li Jue and Guo Si later regretted their decision to let Emperor Xian leave Chang'an, so they led their troops to pursue the emperor.
