Why was Liu Bang attacked by Xiang Yu, when Pengcheng was victorious?

The Book of Han describes this event as follows.

Although Yu heard about the Han East, he both attacked Qi and wanted to break it and then hit the Han, so the Han King robbed the five princes and soldiers to attack Chu in the east. To Waihuang, Peng Yue returned 30,000 people to Han. The king of Han worshiped Yue as Wei Xiangguo, and ordered Dingliang also"

The king of Han then entered Pengcheng, accepted bribes from Yu beauties, and set up a wine party. Yu Wenzhi, so that it will be killed, and since 30,000 elite soldiers from Lu out of Huling, to Xiao, the morning attack on the Han army, the battle of Pengcheng Lingbi East Suishui, the Han army, more killings, Suishui for the flow"

During this period, there was no mention of Zhang Liang and where they were. But it can be speculated that Liu Bang was already dazed by the victory at this time, and he was not as able to listen to opinions as he was when he entered the customs, and Peng Cheng won far more victories than he won in the customs first, and he was no longer Liu Bang who was new to the customs at that time. It can be said that the victory made his brain hot, and even if he had an opinion, he would not listen.

As for the hundreds of thousands of rebels mentioned above, it seems that there is no basis for it, right? Moreover, Xiang Yu is a prodigy of generals after all, although he is not as good as Liu Bang in terms of employing people, but he is much higher than Liu Bang in terms of military affairs. There is a reason for the defeat of Pengcheng.

Because Xiang Yu couldn't bear to kill Liu Bang, he felt that Liu Bang couldn't pose a threat to him, so he let him go, but he didn't expect to die in the hands of Liu Bang in the end.

Xiang Yu and Liu Bang were both overlords of Western Chu, and their battle lasted for a long time, although Liu Bang was defeated, Xiang Yu also had no ability to kill Liu Bang.

I don't think it's careless, because Xiang Yu is very easy to be soft-hearted, and he didn't want to kill Liu Bang in the first place, because Liu Bang can be used by him.

The reason why Xiang Yu failed to eliminate Liu Bang in the Battle of Pengcheng was because Liu Bang's escape was very good, and Han Xin arrived in time to prevent Liu Bang's rout.

I think it's really because of carelessness, but it's still Xiang Yu's temporary soft-heartedness, because Xiang Yu is a very affectionate person.

I want to be careless, but I also want Xiang Yu to be soft-hearted, because Xiang Yu is very affectionate.

Because Xiang Yu loves beauties more than he loves the country.

Because Liu Bang has no combat experience, he is not as powerful as Xiang Yu. In addition, the terrain is not advantageous.

Because Liu Bang's army was all peasants, they had not undergone professional and orderly training, but Xiang Yu's army was particularly imposing.

On the one hand, because Xiang Yu and his army are brave, and Xiang Yu's tactics are obtained. On the other hand, because Liu Bang's soldiers were gathered by princes from all walks of life, they were not strictly organized and did not undergo strict training.

Mainly because Liu Bang's strength was not very strong at that time, although he had soldiers, he would not use them. I just know how to punch.

Because the enemy he was facing at this time was Han Xin, the embattled army directly exhausted the morale of the Chu army, and what was waiting for Xiang Yu was Wujiang to kill himself.

The situation is different, and Xiang Yu no longer has such a strong strength by then.

Because Xiang Yu had no soldiers at that time, and the capable people around him were basically gone.
