Just as Han Xin was preparing to attack Qi, Liu Bang sent Li Yiji to persuade Tian Guang (King of Qi) to surrender without informing Han Xin. Tian Guang decided to surrender and ordered his troops to withdraw from Lixia (歷下; present-day Jinan, Shandong). However, Han Xin was not aware that Tian Guang had the intention of surrendering, so he followed Kuai Tong's advice to attack Qi. Han Xin's army conquered Lixia and attacked the Qi capital, Linzi. Tian Guang thought that Li Yiji had lied to him so he executed Li and retreated to Gaomi, where he requested aid from Western Chu. Meanwhile, Han Xin conquered Linzi and continued to pursue the retreating Qi forces to Gaomi.
