Liu Bang left Hanzhong, settled in Sanqin, and took Cheng Peng, the capital of Xiang Yu. Later, he was defeated by Xiang Yu and fled to Xingyang to gain a foothold. Then Liu Bang and Xiang Yu fought on the frontal battlefield, and ordered Han Xin to lead the troops to the north, pacify the whole north of the Yellow River, relieve the security of the Han army, and further attack the forces supporting Xiang Yu, thinking that they would eventually defeat Xiang Yu and set a strategy. Han Xin and Zhang Er led an army to attack Zhao. At that time, the monarch of Zhao was Zhao Wangxie, the military commander was Chen Yu, and Li Zuoche was Chen Yu's counselor. At that time, Li Zuoche put forward an idea to Chen Yu: Han Xin came from afar and went deep alone, so he could defend heavily under the narrow Jingxing mouth. At the same time, he sent troops to attack the grain delivery troops in Han Xin. He would guard the city and avoid fighting. It won't take long to defeat Han Xin.
But Chen Yu wouldn't listen. Chen Yu thinks that the teacher of justice didn't use Li Zuoche's stratagem. Later, in the battle of Jingxing, Han Xin lured the enemy out of the city with last stand and ambushed the Indiana Jones at the same time. Then he occupied the city, changed its name and defeated Zhao. Without resistance, he was killed by the disorderly army, and Zhao was wiped out. It was because of this war that Han Xin heard about Li Zuoche's plan. After the war, Han Xin begged Li Zuoche to be captured with his daughter, and regarded Li Zuoche as a teacher, and asked Li Zuoche for advice on the plan to break the Qi and Yan States.
Suggest Han Xin: First, stay put, rest the soldiers, appease Zhao, reward the soldiers, and put on a posture ready to attack Yan. At the same time, messengers were sent to lobby Yan to surrender. After Yan surrendered, he sent an envoy to Qi, letting Yan and Qi surrender without fighting. Han Xin adopted Li Zuoche's stratagem to make Yan surrender. Later, when he was ready to attack Qi, Liu Bang, with the troops of Han Xin and Zhang Er, sent messengers to Li Zhi to lobby Qi to surrender. Li Zhi successfully completed the lobbying task, and Qi has promised to surrender, but Han Xin still sent troops to attack Qi and won Qi.
Han Xin's great military talent aroused Liu Bang's suspicion. In order to contain Han Xin, Liu Bang transferred Li Zuoche from Han Xin, transferred Li Zuoche to Liu Yuxin Ying, and let Li Zuoche teach Liu Ying to study and train. At that time, Liu Yuxin stayed in Xingyang, and Li Zuoche taught Liu Ying to train on the mountain outside Xingyang, which was later named Guangwu Mountain. Guangwu is the national name of Li Zuoche. In memory of Li Zuoche, the mountain was named after Li Zuoche. At that time, Liu Bang was fighting against Xiang Yu at the front, and he had been fighting abroad for many years. He seldom goes back to Xingyang to be with him. In addition, Liu Bang was already partial to Mrs Qi, and his relationship with Liu Ying was relatively distant. Li Zuoche assisted Liu Yuxin, who had basically never seen Liu Bang, let alone advised Liu Bang.
At that time, Sean, Chen Ping and others in the army advised Liu Bang. Liu Bang didn't need Li Zuoche, but in order to balance Han Xin, he was transferred to Li Zuoche. After Han Xin was killed by Lv Zhi, Zuo Lier resigned and went home. His story is unknown.
