When Chu and Han contended, Han Xin, the marquis of Huaiyin, held a good soldier, but he never took the initiative to lead the troops to Xingyang to help Liu Bang. Instead, he took a similar wait-and-see action for three reasons.
First of all, Han Xin's task is not to "save Liu Bang", but to destroy some vassal states for Liu Bang.
In the second year of the Han Dynasty, Chen Ping, who later became the Han Dynasty, returned to the Han Dynasty. As soon as Chen Ping arrived in Han Ying, he submitted a plan to Hanwang Liu Bang. According to historical records, this plan is that Liu Bang plundered five vassal soldiers and conquered Chu. The plan is going well.
At that time, Xiang Yu was fiercely resisted by Qi people because of burning, killing and looting in Qi, so he had to stay in Qi to deal with Qi people. At the same time, Cheng Peng, the capital of Xiang Yu, is very empty. Liu Bang's Han army and the plundered five governors quickly won Cheng Peng, and Hanwang Liu Bang lived in the Overlord Palace, occupied Xiang Yu's concubines and treasures, and met in the Overlord Palace every day.
Xiang Yu forgot the resistance of Qi people and returned to Cheng Peng with a good soldier. Liu bang, who was carried away by victory, was caught off guard, and the five princes and soldiers were immediately neutral. Liu Bang led the Han army to fight alone and lost to Xiang Yu's elite soldiers. More than 100,000 Han troops were forced to the water by Xiang Yu's Chu army and suffered heavy casualties.
After Cheng Peng's defeat, Liu Bang finally ran out of the encirclement of the Chu army. In Xiayi, Liu Bang dismounted, leaned on the saddle and made a big wish. If someone can help him win the world, he can give up all the land east of Shanhaiguan. Liu Hou Sean took this opportunity to recommend Ying Bu, Peng Yue and Han Xin. Back in Xingyang, Liu Bang sent Han Xin to conquer the Western Wei Dynasty in Wei Bao. Han Xin lived up to his mission and captured Wei Bao alive in World War I. Liu Bang also paid more attention to Han Xin, gave him tens of thousands of military forces, and asked Han Xin and Zhang Er, the old Changshan king, to pacify Zhao. After Han Xin pacified Zhao, he forced Yan to surrender, and Liu Bang ordered Han Xin to cut Qi.
Various evidences show that, as a general of Liu Bang, Han Xin's task is to send troops for Liu Bang and conquer the vassal states. So, when Han Xin didn't finish the task, there was no need to personally lead troops to support Liu Bang.
Secondly, Han Xin's ambition is to crack the soil and be king, and only when the soldiers are outside will they have a chance to crack the soil and be king.
Sima Qian, a great official, had been to Huaiyin County, the hometown of Han Xin, before compiling Historical Records. In Huaiyin County, Sima Qian found many anecdotes about Han Xin. Sima Qian knew before he made his fortune that Han Xin's ambition was different from that of the people around him, which can be seen from Han Xin's burial of his mother.
Before Han Xin made his fortune, his life was miserable, and he couldn't even support himself, so he had to follow others for free. But Han Xin was so poor, but he could find a tall and spacious cemetery for his mother after her death. Sima Qian has been to Hanmu Cemetery, and found that the cemetery has good geomantic omen, and 10,000 families can be put next to it.
Han Xin's mother's funeral showed that Han Xin's ambition before he became rich was to be king, or at least to become Wan Huhou.
In order to realize his ambition, when Xiang Liang and an uncle of Xiang Yu led an army to Huaiyin, Han Xin took the initiative to join the army. When Han Xin was in Xianggudui, he tried many times to display his talents and made suggestions to Xiang Yu, but unfortunately none of them were adopted. Han Xin turned his back on Chu and left for the Han camp. Han Xin thought that Xiao He had recommended himself to Liu Bang many times, but Liu Bang still didn't reuse himself, thinking that he had no chance, so he fled again, which led to the historical story of Xiao He chasing Han Xin under the moon.
