The Chu and Han sides were at a standstill on the line of Xingyang and Chenggao, and Han Xin successively eliminated the princes and kings of the wall-riding faction and implemented a strategic encirclement of Xiang Yu's troops.

In the autumn of 205 BC, Han Xin led a surprise attack and besieged the Wei capital city of Anyi (east of Yuncheng, Shanxi), and the Wei king Wei Bao surrendered.

In the leap September of the same year, Han Xin led the army to capture the acting minister Xia said.

In 204 BC, Han Xin fought against the water, defeated the Zhao army, beheaded the acting king Chen Yu, and captured Zhao Xie, the king of Zhao. Subsequently, Yan Wang Zang Di surrendered.

At this time, Liu Bang sent Li Shiqi to persuade Qi Wang Tianguang to surrender. Li Shiqi was a famous lobbyist in the late Qin Dynasty and contributed a lot to Liu Bang's united front work. When Li Shiqi arrived in the Qi country, he persuaded Tian Guang to give up his war preparations and surrender more than 70 cities in Qi.

When Han Xin heard the news and was about to withdraw his troops, his advisor Kuaitong persuaded: "You have worked hard to conquer more than 50 cities, and you have persuaded more than 70 cities to surrender with your mouth, and your merits have been compared, so it is better to take advantage of the lax defense of Qi and capture the Qi State." ”

Han Xin listened to Kuaitong's words and attacked Qi State. Tian Guang, the king of Qi, fled to Gaomi. Tian Guang thought that he had been deceived by Li Shiqi and killed him.

Tian Guang asked Xiang Yu for help. There are no eternal friends, only eternal interests. Xiang Yu let go of his past grievances and sent the general Long He to lead the troops to rescue Tian Guang and work together to fight against the Han. The number of Qi-Chu coalition troops is claimed to be 200,000.

Long He led the army and the Han army across the Weishui (Weihe, Shandong) east and west to set up a position. Han Xin ordered the soldiers to make more than 10,000 bags overnight, filled with sand and soil, blocking the upper reaches of the Wei River, making the river shallow.

The next day, half of the Han army waded through the water to attack the enemy position, and Long He sent troops to meet the attack, and the Han army feigned defeat and retreated. Long and eager to win, and thought that Han Xin was timid and weak, so he led the army to cross the river and attack.

At this time, Han Xin ordered people to break open the sandbags that blocked the Wei River, the river rushed down, the soldiers on the riverbed were washed away by the water, and the coalition troops who had crossed the river were stranded on the west bank, and the formation was in chaos.

The Qichu coalition army, which was still on the east bank, saw this scene and fled in all directions. Han Xin led his army across the river in pursuit. Tian Guang, the king of Qi, was killed, and the state of Qi perished.

Han Xin pacified the five countries in a row and made great contributions, and it can be said that most of the Han Dynasty was defeated by Han Xin. Han Xin also made a big mistake, in order to grab credit, he violated Liu Bang's united front policy, causing Li Shiqi's tragic death. When the matter reached Liu Bang's ears, what would Liu Bang think.

A few years later, Liu Bang was awarded the title of meritorious hero, thinking of Li Shiqi, and made an exception to seal Li Shiqi's son Li Scabies as the Marquis of Sorghum. A rift between Liu Bang and Han Xin is inevitable.

Han Xin was full of ambition at this time, and wrote to Liu Bang and said: Qi people are cunning and difficult to govern. I request to be the false king of Qi (acting king of Qi) in order to stabilize the situation.

Liu Bang was furious when he saw the book, and scolded as soon as he opened his mouth: "I am waiting for you to bring troops to help me every day, but you are thinking about what kind of fake king Qi you are!" ”

Zhang Liang and Chen Ping both stepped on Liu Bang's feet under the table. The messenger is standing in front of him. Liu Bang immediately reacted: Han Xin is still needed, and he can't tear his face yet.

He immediately changed his words and scolded again: "If the husband wants to be a real king, what kind of false king!" Zhang Liang was immediately appointed as the canonization envoy and Han Xin was appointed as the king of Qi.

Han Xin was overjoyed and moved. The seeds of distrust have sprouted in Liu Bang's heart. Sima Guang of the Song Dynasty wrote in "Zizhi Tongjian", "At that time, Liu Bang already had the heart to seek Han Xin", and he was forced to use Han Xin due to the situation, so he had to temporarily forbear. Mr. Sima Guang sighed with emotion: Han Xin can't serve the monarch wholeheartedly, but he expects the monarch to treat himself wholeheartedly, which is not difficult!

At any time, it is wrong to reach out to the organization to ask for a position and salary, let alone when the war is urgent, and it is even more suspected of blackmailing the monarch.
