The famous saying "Although there are three Chu families, the Qin Dynasty will be destroyed" originated from Sima Qian's Historical Records of Xiang Yu in the Western Han Dynasty. It means that although only a few families can destroy the state of Qin. Although the metaphor is small, you can succeed with great determination. It represents an emotional and firm belief, and what is even more incredible is that it coincides with the process of historical evolution.

Qin always cheated Chu people, making Chu miserable. In a rage, the King of Chu sent troops to attack Qin and lost the battle. Qin people invited Chu Huaiwang for peace talks, but they captured the king of Chu, making him die in a foreign land. Therefore, Chu people hated Qin deeply.

Because Chu was a country with the greatest strength in unifying the world in economy and agricultural military affairs at that time, Zhao's folkways and customs were constantly hit by Qin. Most of the time in a passive position, Qin Jun killed 4, soldiers in the battle of Changping, and then it was invaded by Yan. Although Zhao defeated Yan, it dealt a blow to Zhao at one time and later lost Li Mu, so Zhao lost its final strength to compete with Qin. Other countries have developed economies, but their military strength is still almost the same. The overall strength of Chu is still very strong. If the military command is accurate, and the talents of Chu can compete with Qin!
