At the end of the Qin Dynasty, Chen Sheng and Wu Guang raised troops against Qin in Daze Township, and all parts of the country responded, and for a time the world was anti-Qin, and Chen Sheng proclaimed himself the king of Chu and established the so-called Zhang Chu regime, but Chen Sheng was soon killed in the war. Although Chen Sheng died, the seeds of anti-Qin sown by Chen Sheng had taken root and sprouted in various places, so the pace of anti-Qin in various places not only did not stop, but had the tendency to burn the prairies. 
Especially after Xiang Yan, a famous general of the Chu State, Xiang Liang also raised troops in Huiji, and faintly became the strongest anti-Qin force with the strongest appeal and strength after Chen Sheng. Therefore, Xiang Liang once convened all the generals to discuss the anti-Qin plan after Chen Sheng's death, and it was at this time that Fan Zeng gave Xiang Liang an idea: "Chen Sheng's defeat is solid." Fu Qin destroyed the Six Kingdoms, and Chu was the most innocent. Since King Huai entered Qin, the people of Chu have pitied him so far, so the Duke of Chu Nan said, "Although Chu has three households, the death of Qin will be Chu". Today, Chen Sheng's first thing, not to stand on his own after Chu, his momentum is not long. Now the monarch starts Jiangdong, and the generals of Chu Bee Wu are all vying for the monarch, and the generals of Chu in the world are also able to restore Chu. Xiang Liang listened to Fan Zeng's suggestion and searched for the descendants of King Chu Huai among the people, and as a result, Xiong Xin, a grandson of King Chu Huai, was found and re-established as King Chu Huai. 
Many people may have a question when they see this, why did Xiang Liang let King Chu Huai be the leader of this uprising, which is quite a bit of the co-lord of the world, to increase his strength, instead of choosing to let the descendants of Zhou Tianzi bear this responsibility, after all, Zhou Tianzi has been the co-lord of the world for 800 years? And many people in later dynasties are nostalgic for the Zhou Dynasty, so is it that people also miss Zhou Tianzi at the end of Qin? This is obviously impossible, not that the Zhou Dynasty fell early, in fact, the Zhou Dynasty really fell in 256 BC, and Chen Sheng and Wu Guang opposed Qin in 209 BC, which is actually not a very long time apart, it can only be half a century, if Zhou Tianzi is really appealing, it will not lose its prestige in such a short time. The problem lies here, in fact, long before the fall of the Zhou Dynasty, Zhou Tianzi had already lost his appeal, and Zhou Tianzi really had appeal in the Western Zhou Dynasty, when Zhou Tianzi was indeed the real co-lord of the world, and the various vassal states defended the Western Zhou Dynasty. However, in the year of the Western Zhou Dynasty, the Western Zhou Dynasty gradually declined, and the King of Zhou You accidentally attracted the combined siege of Shen and Zhangguo and Dog Rong and died. 
King Zhou Ping finally recovered the country with the help of several princes and kings, the army of the Zhou Dynasty was greatly reduced, and the king of Zhou Ping moved eastward and lost a lot of land. During the Spring and Autumn Period, the princes still had a certain degree of respect for Zhou Tianzi, and they could also call on the princes of the world to raise the banner of respecting the king. And in the Warring States Period, Zhou Tianzi's prestige further declined, his existence was no longer feared by the Seven Heroes of the Warring States Period, and the demise of the Eastern Zhou Dynasty was only time, the reason why everyone did not move Zhou Tianzi was just because he didn't want to be truthful and famous by other vassal states, and at the end of the Warring States Period, the powerful King Qin Zhaoxiang already felt that it was time for Zhou Tianzi to disappear, so the Eastern Zhou Dynasty was gone. If it is said that in the Spring and Autumn Period, if Zhou Tianzi came out to say something, there would still be a prince to listen, but in the Warring States Period, Zhou Tianzi's right to speak was not even as good as a small prince, and it was not that a prince did not regard Zhou Tianzi as the co-lord of the world, but that all the princes no longer regarded Zhou Tianzi as the co-lord of the world. 
Since there is such a situation, how could Xiang Liang be so stupid as to continue to let Zhou Tianzi's descendant, the new Zhou Tianzi, be the co-master of the world? I don't add strength to myself at all. And King Chu Huai is different, there are several reasons why King Chu Huai can be respected as the co-master of the world. First of all, most of the forces that stood up against Qin at that time were Chu people, and they gathered on the land of Chu and then opposed the rule of the Qin Dynasty, so naturally letting the descendants of the king of Chu be the co-masters of the world is the best way to capture the hearts of the people, and the best to accumulate strength for Xiang Liang and unite most of the anti-Qin forces for their own use. Secondly, when the Qin Dynasty destroyed the Six Kingdoms to unify the world, the resistance of the Chu State was the most intense, and most of the Warring States Period was the largest territory of the Chu State, and the patriotic heart of the people was stronger. 
But even if it was destroyed by Qin, the Chu people always remembered the hatred of Qin to destroy Chu, so the Chu Southern Guild said: "Although Chu has three households, if Qin dies, Chu will die." Whether this sentence is hindsight, we don't know, but it can also be seen that the Chu people have a deep hatred for the Qin Dynasty. Therefore, we see that most of the generals who opposed Qin at the end of Qin came from the former Chu State, and from this aspect, the descendants of the King of Chu as the co-masters of the world are the most able to buy people's hearts. Again, this is going to involve the former King of Chu, King Chu Huai. King Chu Huai was a politically naïve person, he was a bit similar to Song Xianggong in the Spring and Autumn Period, but a little out of place. At the beginning, Song Xianggong in the battle of Hongshui with King Cheng of Chu, facing the self-proclaimed barbarian Chu State, Song Xianggong insisted on the so-called war etiquette, did not attack the Chu army when they crossed the river, nor did they attack the Chu army when the Chu army did not open the formation, so that the opportunity was missed, resulting in a great defeat, Song Xianggong was injured in the war and died of illness half a year later. 
And King Chu Huai is also out of place, in the Warring States Period, which was already full of intrigue and intrigues, he actually believed Zhang Yi's words, completely broke off diplomatic relations with Qi State, and also got the six hundred miles of land sent by Qin State, but when King Chu Huai sent an envoy to Qin State to do this, Zhang Yi only promised to give six miles of land. It stands to reason that being deceived by Zhang Yi like this, King Chu Huai should not believe him anymore. And then no, after King Chu Huai finally got Zhang Yi and locked him in prison, Zhang Yi indirectly got in touch with Zheng Sleeve, and Zheng Sleeve persuaded King Chu Huai to release Zhang Yi. As a result, Zhang Yi took the opportunity to persuade King Chu Huai to form an alliance with Qin, and King Chu Huai happily agreed. This matter seems to have little impact, but in fact, it is precisely because of Zhang Yi's engagement, that the prince of Chu Huai is close to Qi and back to Qi, pro-Qin and then pro-Qin, which can be described as half-hearted, Qi also attacked Chu, and Qin also came to attack Chu, causing Chu to lose a lot of land. This is not counting, later King Qin Zhaoxiang captured the eight cities of Chu State, and asked King Chu Huai to meet in Wuguan, many people thought that this was a trap given by King Qin Zhaoxiang to King Chu Huai, so he persuaded him not to go, but King Chu Huai was afraid of King Qin Zhaoxiang, and he also had a fluke mentality that King Qin could not do anything to him. 
As a result, he never returned, and was detained by King Qin Zhaoxiang in King Qin, King Qin Zhaoxiang tried to sign an unequal covenant with him, King Chu Huai is a hard bone, and would rather not return to Chu for the rest of his life than sign, so he stayed in Qin for three years, during which he escaped, but he was unsuccessful, and finally died of depression in Qin State, this incident made the Chu people very angry, and the dignified monarch of Chu State was actually under house arrest in Qin State and could not return to death, how could Chu people endure it? It's just that the strength of Chu State has declined dramatically at that time, and it has lost the qualification to fight hard with Qin, and this hatred can only be buried deep in the heart, and when there is a suitable soil, this hatred will still take root, and the end of Qin is a good opportunity, so Xiang Liang found the descendants of King Chu Huai and named him King Chu Huai again, which is to arouse the hatred of the Chu people against the Qin Dynasty, and then join the anti-Qin team. Of course, although King Chu Huai seemed to have become the co-lord of the world, in fact, he was only subject to the Xiang family, and King Chu Huai was finally killed by Xiang Yu.
