Xiang Yu and Liu Bang signed the Gap Treaty, why did Liu Bang immediately tear up the treaty?

Because of Zhang Liang and Chen Ping.

It was suggested that the peace treaty be torn up and attack the Chu army from behind, so Liu Bang.

He personally led the remaining million people in the headquarters to pursue.

Xiang Yu was furious, led the army to counterattack, annihilated 400,000 Han troops, Liu Bang had to retreat to Xuzhou, and hurriedly asked for reinforcements from all walks of life to support: that day, after reporting to each other, the kings led the troops to come.

All the generals came to report the number and wait for the adjustment. The letter asked the ovary and Peng Yue to discuss together, referring to Jiuli Mountain as the heart. East to Dingguo Mountain, south to Phoenix Mountain, north to the big river, all directions, with the high and low, valley streams, each ambush 24 places.

Hou Han. Will be out, all of them were killed by Xiang Yu, and no one could stop them from rushing back and forth in the millions of troops, and finally God wanted to destroy Xiang Yu, and Yu had to kill himself in Wujiang.

It is nonsense to say that Sima Qian portrayed Xiang Yu as a hero.

In the Battle of Julu, Xiang Yu led tens of thousands of troops to defeat the main force of the 400,000 Qin army commanded by Zhang Han.

In the battle of Pengcheng, Xiang Yu's 30,000 elites defeated Liu Bang's 560,000 army.

Before the age of thirty-one, he became the strongest in China. This is not what a hero is!

Xiang Yu's failure is due to personality problems, to put it bluntly, he is overconfident, over-inflated, and self-righteous.

It was also Liu Bang who won, so he could smear Xiang Yu as much as he wanted. The chasm treaty was obviously used by Liu Bang to paralyze Xiang Yu. Tearing up the treaty caught Xiang Yu off guard, because Liu Bang never won Xiang Yu in a frontal battle without conspiracy.

In the end, he also relied on the absolute force to crush and Han Xin's ambush on all sides to defeat Xiang Yu on all sides. And if Xiang Yu is willing to cross the river to avoid the war for one or two decades at this time, who can win against Han Xin and Liu Bang after they are a fart!

In order to save his family, Liu Bang temporarily agreed to Xiang Yu to negotiate peace, and then Xiang Yu released the detained Liu Bang's family, and when the family was released, of course they would tear up the treaty.

Liu Bang's signing of the agreement is a strategy, and there is no faith in fighting, that is, to attack Xiang Yu when he is unprepared.

Because, he didn't accept this agreement in his heart, and signing the agreement was just a delaying measure, and he didn't intend to abide by it.

When Xiang Yu had the upper hand, he didn't get Liu Bang up and let him make a comeback! Liu Bang was deeply touched, and at this time he had the upper hand. Don't kill Xiang Yu! Who can guarantee that Xiang Yu will not make a comeback.

The signing of the chasm treaty was just a delaying tactic, they were originally hostile, and it was normal for them to break the contract.

Because Liu Bang's family was hidden by their shirts at that time, they had to come to you to sign this treaty to do things, and his Wan Bingzhi residence.

No one stipulates that they must abide by the signing of the agreement, they are originally hostile relations, and signing the agreement may be a ploy, and it is no wonder that the breach of contract.

Because Liu Bang's people were in the hands of others at that time, Liu Bang had to sign such a treaty. This is also quite normal.

Because Xiang Yu didn't want Liu Bang to get the title of "King of Guanzhong", he deliberately changed the concept and named Liu Bang the "King of Han". King Chu Huai originally agreed: "The one who enters the customs first is the king", which means:

Whoever enters Guanzhong first is the king. That is, Liu Bang should be named the "King of Guanzhong". Since Xiang Yu refused to abide by the agreement, and did not want to bear the notoriety of the contract, he conspired with Fan Zeng to find a way.

Xiang Yu's final solution was to change the concept and make Guanzhong the same as Qin, and then Hanzhong and Bashu were also Qin lands, so Liu Bang was named the "King of Han" and the king of Bashu and Hanzhong.

Guanzhong as a place of four stops, the terrain is dangerous, the population is rich, the advance can be attacked and retreated, and it is the treasure land of the king and hegemony. Xiang Yu categorically refused to let Liu Bang, who had already gained fame and fortune, occupy this place.

It was because Xiang Yu thought that Liu Bang was a greater threat to him, because Liu Bang did not follow his orders and directly attacked the capital of the Qin Dynasty.

According to the "Historical Records", "the gap and the west are Han, and the gap and the east are Chu." In this way, history has made the chasm "Chu River Han Boundary". As the gap of the "Chu River Han Boundary", it is in Xingyang City, Henan Province.

Why did Xiang Yu and Liu Bang use the chasm as the boundary at that time? The main reason is: Xiang Yu is anxious to make peace and to get out of the passive and dangerous situation.

At this time, there may be many people questioning, according to the "Historical Records of Xiang Yu Benji", it should be Liu Bang who is eager to seek peace, in fact, everyone should have been deceived by Sima Qian, and the chasm agreement recorded in the historical records is likely to be another big lie laid by Sima Qian in order to make Xiang Yu a hero.

We can also analyze some clues based on the historical facts at that time. At that time, Xiang Yu was far away from the feudal country, the grain route and the back road had been cut off, and the Han army Liu Jia and Han Xin had formed an encirclement of the Western Chu State from the north and south. Xiang Yu's general Long He was killed, and the northern part of the Western Chu State was completely exposed to the attack of the baby.

Xiang Yu stuck to the isolated city of Xingyang, and his soldiers and grain and grass were exhausted, and he could be surrounded and annihilated by the Han army at any time.

However, Liu Bang successfully used the Xingyang and Chenggao blocking battles to attract the main forces of Xiang Yu and the Chu army, and took the opportunity to seize Zhao, Wei, Qi, Yan, Chu and other large territories. The two lines of defense in Chenggao and Gongxian have been held for two years and four months, which can be described as impregnable. Behind it is the vast base area in the Guannai, where the soldiers have a steady stream of food and grass, and in front of them is Xiang Yu at the end of the strong crossbow.

Even if it drags on any longer, there will be no damage to Liu Bang.

Therefore, it can only be Xiang Yu who is eager to make peace, not Liu Bang.

Of course, Xiang Yu is seeking peace for himself, and Liu Bang has no real intention of keeping the contract and coexisting peacefully with Xiang Yu. The two of them had their own plans, and after signing the agreement, Xiang Yu's escape did not make him escape safely. Soon, Liu Bang's pursuers arrived, and in the south of Yangxia City, 200 kilometers away from Xingyang, the Han army caught up with the Chu army, and then there was the matter of Xiang Yu killing the Wujiang River.

The chasm was the earliest artificial canal connecting the Yellow River and the Huai River in ancient China. It is located in the ancient Xingyang Chenggao area, now Xingyang, Zhengzhou, Henan Province. Construction began in the tenth year of King Wei Hui of the Warring States Period (360 BC) during the Eastern Zhou Dynasty.

After completion, it has been one of the main water transportation routes in the Central Plains between the Huanghuai and Huai through the Qin Dynasty (221 BC and 206 BC), the Han Dynasty (206 BC and 23 AD), the Wei, Jin, and Northern and Southern Dynasties (220 AD and 581 AD). During the Western Han Dynasty (206 B.C., 23 A.D.), it was also known as the Wolf Soup Canal. The place is bordered by the Yellow River in the north, the mountain in the west, the great plain in the east, and the Zhongyue Song Mountain in the south.

Judging the Gap is from the "Historical Records of Xiang Yubenji", which describes the boundaries clearly and the difference is very large. The chasm was a river in ancient times, and in today's Henan Province, it was a river that divided Chu and Han at the end of the Qin Dynasty.

Of course, Xiang Yu and Liu Bang were at a stalemate, and both sides were facing the problem of insufficient food and grass, so they agreed to take the chasm as the boundary, divide the world equally, and neither would cross the chasm.

Liu. Xiang Yu is the chasm of the boundary.

It's like the Chu River Han realm on the chessboard of chess.

meaning. Liu Bang Xiang Yu. The two met, with the "chasm" as the boundary, the world was divided, and the west of the chasm belonged to Liu Bang, the king of Han, and the east belonged to Xiang Yu, the overlord of Chu.

That chasm. Approximately.

The chasm, that is, the canal, the old river channel diverts the water of the Yellow River from the north of Xingyang County, Henan Province, passes through the north of Zhongmu County in the east, reaches the south of Kaifeng City, flows through the east of Tongxu County and the west of Taikang County, and flows into Yingshui from the southeast of Huaiyang County.

At that time, the chasm was a river in ancient times, located in today's Henan Province, and at the end of the Qin Dynasty, it was a river that divided the Chu and Han dynasties. At the beginning of the war, Xiang Yu and Liu Bang had about the same strength, and they couldn't attack each other, and then agreed to use the chasm as the boundary, divide the world equally, and go their own way.

Xiang Yu Liu Bang to the chasm as the boundary, the chasm refers to the canal, the chasm is now Xingyang, Henan, the ruins of the Han Dynasty City and the Overlord City on both sides of the old chasm are still there, and now it has become a tourist attraction.

The approximate location of the chasm is in Xingyang City, Henan Province, and the ruins of the Han Dynasty City and the Overlord City on both sides of the old chasm are still there, and have become tourist attractions.

It was excavated by King Wei Hui during the Warring States Period for war. The old canal flows from the north of Xingyang County, Henan Province, through Zhongmu County in the east, to the south of Kaifeng, and flows into Yingshui from the southeast of Huaiyang County.

In Xingyang City, the ruins of the Han Dynasty City and the Overlord City on both sides of the old chasm are still there, and it has become a tourist attraction.

Qinling Huai River.

Liu Bang was in Sichuan before.

To get out of Shu, to get out of Qinling.

"The chasm refers to the ancient canal, in present-day Xingyang City, Henan Province, the ancient passage connecting the Yellow River and the Huai River. When Chu and Han fought each other, it was the temporary border of the confrontation between the two armies of Liu Bang and Xiang Yu. During the Western Han Dynasty (206 B.C., 23 A.D.), it was also known as the Wolf Soup Canal.

Historical Records: Xiang Yu Benji":"King Xiang is a covenant with the Han Dynasty, dividing the world in the middle, cutting the gap to the west for the Han, and the gap to the east for Chu. "It means that Xiang Yu and Liu Bang agreed to divide the world equally and take the chasm as the boundary.

The Chu-Han River boundary is a very famous chasm in history, but this chasm has been gradually dried up due to countless wars and the movement of the earth's crust, leaving only very few historical relics in modern society。We all know that the confrontation between Liu Bang and Xiang Yu is not short, the two have experienced a long time from the disparity in strength to the later rivalry, during which they tried to make peace for various reasons, of course, there are also frauds, for example, Liu Bang once drew the chasm, with the chasm as the boundary, do not interfere with each other, and divide the country into two halves, but in the end Xiang Yu was forced by Liu Bang to the other half of the chasm and killed himself.

This chasm is not a small ditch like a river, it already existed during the Warring States period。It was first excavated in the period of King Wei Hui, when the whole country of Wei moved to the capital of Daliang, but the traffic of Daliang is not convenient at all, and sometimes it is blocked everywhere, so King Wei Hui paid attention to hitting the Yellow River and the Huai River, when he used a lot of manpower and material resources to dig a big ditch between the Huai River and the Yellow River, this is the chasm that Liu Bang said later, this chasm is very large, and can also be used for shipping, it can be said that the waterway extends in all directions, The national strength and economy of Wei have been greatly improved.

Xiang Yu's hometown of Pengcheng is close to the chasm, this chasm has greatly improved the food production of the neighboring cities, and the aquatic products are also quite rich, the life of the local people can be said to be quite rich, which is why Xiang Yu wants to return to Pengcheng very much, in addition to the hometown, there is also a very important point, that is, the average living standard of the people is relatively high, so it is very comfortable to live here. After Xiang Yu's defeat, Liu Bang established the Western Han Dynasty, and the Western Han Dynasty also attached great importance to this gap, and connected the industries of various places through this gap, so that the economy of the Western Han Dynasty, which had just been established at that time, had developed to a certain extent.

However, later on, the Yellow River flooded, and the cover of the Bianqu led to the name Bianshui, which slowly dried up and disappeared as the environment changed.

The chasm is a big ditch dug by King Wei Hui in order not to be plywood, and the whole chasm is excavated from Xingyang, leading the water of the Yellow River, passing through today's Zhongmu Kaifeng and other places, and finally flowing into the Huai River through the Yinghe River. After wars such as the rare Peasant War, the chasm water system was invaded by a large amount of sediment, and to this day, only some remnants of history remain.

The chasm is a canal that existed during the Warring States period and flowed from Xingyang to the Huai River through the Yinghe River, and later due to the flooding of the Yellow River, a large amount of sediment was completely paralyzed and disappeared.
