2. The origin of the allusion to the Han realm of the Chu River.

In 203 BC, Liu Bang sent troops to attack Chenggao of Chu State, and the guard general Cao Ji could not withstand Liu Bang's sergeant who went to the city many times to call for insults, so he angrily led his troops out of the city, wanting to cross the river to fight against the Han army. When the boat reached the river, it was attacked by the Han army and defeated, Cao Ji regretted it, and knew that he had no face to see Xiang Yu, so he committed suicide.

Liu Bang successfully captured Chenggao and garrisoned Guangwu. After Xiang Yu learned that Cheng Gao was lost, he immediately dispatched troops to the rescue. In order to force Liu Bang to surrender, Xiang Yu pulled the captured father of Liu Bang to Guangwu Mountain (now Bawang City) according to the east of the city, and threatened Liu Bang across the stream

If you don't surrender sooner, I'll boil your father to death." ”

Liu Bang pretended to be calm and said, "At the beginning, the two of us fought against Qin together and swore to be brothers, and my father is your father." If you're going to cook our father, don't forget to give me a bowl of broth."

Xiang Yu became even more annoyed after hearing this, and decided to kill Liu Taigong. Under the persuasion of Xiang Bo, "Taigong survived". However, Liu Bang closed the city and did not come out, and sent the general Han Xin to lead his troops to copy the back road of the Chu army and occupy Hebei and Shandong.

Because of the lack of food and soldiers, Xiang Yu had to be forced to put forward the requirements of "dividing the world in the middle, cutting the gap to the west for Han, and the east for Chu", and history made the gap "Chu River and Han boundary".

When I was a child playing chess, I would find that in the two horizontal bars in the chessboard, there were four words written "Chu River Han Boundary", I was very curious at that time, why these four words were written in the middle of the chessboard, and later when I grew up, I gradually became familiar with history, and only then did I know the historical allusions of "Chu River Han Boundary" and the reason for appearing in chess. Some readers and friends still don't know much about this matter, so I will give you a popular science below, what place does "Chu River Han Boundary" refer to, and what is its allusion.

In Chinese chess, there are two horizontal bars in the middle of the chessboard, on which are written the words "Chu River Han Boundary". In fact, this "Chu River Han Boundary" originated from the chasm covenant during the Chu-Han War, when Liu Bang and Xiang Yu agreed to take the chasm as the boundary, the west side of the chasm belonged to Liu Bang's Han, and the east side of the chasm belonged to Xiang Yu's Chu State.

According to the historical records, the "Chu River Han Boundary" at that time was in the ancient Yuzhou Xingyang Chenggao place, it is the Yellow River in the north, Songshan in the south, Kuang Mountain in the west, and a plain in the east.

In 205 BC, the Chu overlord Xiang Yu defeated the Han king Liu Bang at Pengcheng, and Liu Bang had to retreat to Xingyang after his defeat, and for the next two years Chu and Han fought each other for Xingyang.

In 203 BC, Liu Bang, the king of Han, decided to send troops to attack Chenggao, the soldiers of the Han army called for insults many times under the city, and the general of Chenggao of Chu State Cao was humiliated and decided to take the initiative to attack, and on the way to cross the water, he was attacked by the Han army, and the Chu army was quickly defeated. Cao Ji had no face to see Xiang Yu, so he committed suicide after the defeat, and Liu Bang then successfully captured Chenggao. After Xiang Yu learned that Liu Bang had captured Chenggao, he was shocked and immediately led a large army to the rescue.

In order to make Liu Bang surrender, Xiang Yu brought Liu Bang's father, Liu Taigong, as a threat, so that Liu Bang could throw himself into a rat trap.

Later, he shouted at Liu Bang on Xiang Yu's Guangwu Mountain, claiming that if Liu Bang did not surrender, he would cook his father Liu Taigong to death, but Liu Bang responded to Xiang Yu scoundrelly and said that they had rebelled against the tyrannical Qin before, and had made a brotherly covenant, his father was Xiang Yu's father, and if Xiang Yu was going to cook and kill their father, don't forget to share his share. Xiang Yu was furious after hearing this, and wanted to kill Liu Taigong to vent his anger, but fortunately he was stopped by Xiang Bo. Subsequently, Liu Bangbing divided into two routes, one was still in a stalemate with Xiang Yu in Xingyang, and the other sent Han Xin to occupy Hebei, Shandong and other places, so as to disturb and cut off the retreat of the Chu army.

After that, the balance of victory in the war began to tilt to Liu Bang's side, the Han army had a stable rear, Xiao He's grain and grass in the rear were continuously transported to the front line, while Xiang Yu was cut off from the back road and faced the problem of insufficient grain and grass.

In 202 BC, Xiang Yu, who had run out of grain and grass, made peace with the Han army in desperation, and agreed that Chu and Han would be bounded by a chasm, with Han in the west and Chu in the east.

This is the famous "covenant of the chasm" in history, from which the allusion of the "Chu River and Han Boundary" comes from.

"Chu River Han Boundary"It is a famous allusion in ancient China, which originates from a poem in "Chu Ci Lisao": "It will be the top of the mountain, and you can see the mountains at a glance; The peaks float in the front realm, and the talent of the competition is so bright. This poem depicts the author's magnificent scene overlooking the mountains from a high vantage point, and the remaining three lines express the author's full feelings of homesickness in the face of foreign invasion through metaphors.

The "Chu River" refers to the boundary river between the Chu and Han states, and also represents the dividing line between the two countries of the north and the south. In ancient times, its importance lies in its strategic significance for resisting foreign aggression, so the "Chu River and Han Boundary" has become a place to express the difference between the north and the south, and has been used in literature and art, geography, political science, military science and other fields in history.

Subsequently, "Chu River Han Boundary" was widely used as a popular term in various fields, such as referring to the relationship between two different classes and the boundary between two different fields. In addition, the "Chu River Han Boundary" is also often used to describe the difference between two non-hail and culture, customs, beliefs or status, such as "the two sides of the strait and three places", "urban-rural gap" and other similar concepts can be borrowed from the metaphor of the "Chu River Han Boundary".

In ancient Chinese history, due to regional and cultural differences, there were great differences between the north and the south in many aspects such as politics, economy, and culture, which also made it extremely difficult to achieve national unification. However, it is precisely in overcoming these difficulties that China has formed a pluralistic and integrated national culture, spirit and national identity, and has become a country with a long history and splendid culture.

In short, the allusion of "Chu River and Han Boundary" not only enriches the connotation of ancient Chinese literature and art, but also shows a pluralistic, harmonious and unified development of China.

The extensive influence of the Chu River Han realm in modern culture

In literary works, the Chu River Han realm is used by many writers as a theme or borrowed from its metaphors, such as Yu Hua's ** "Brothers", which writes about the protagonist's journey from the south to the north and through the Chu River Han realm; In Zhu Ziqing's essay "Qinhuai River in the Sound of Oars and Lights", the Qinhuai River is divided into Qinhuai River with "Chu and Han Boundary" and Huaihe River with "Red Water Full River".

In addition, in movies and TV series, the Chu River Han realm is also often used, such as in the movie "The Wandering Earth", the huge difference between the north and the south is described by the Chu River and the Han realm as a dividing line; In the TV series "Dream of Red Mansions", it is used to describe the dividing line between Jiafu and Rongfu, two different cultures, customs and lifestyles.

In short, the allusion of the Chu River and the Han Dynasty not only plays an important role in ancient Chinese history, but also is one of the representatives of traditional Chinese culture, which has deeply influenced modern culture and has become a frequently used word in people's daily life.
