I believe many people have heard this four-word idiom. In fact, this four-character idiom comes from a historical allusion. The protagonist in this historical allusion is very famous. So who is the protagonist of the siege, who is the story of the characters, and what is the historical event? Please come with me to master it.

The embattled master is the descendant of Xiang Yu, the overlord of the place of Chu, the surname and name of the Zhou royal family, a native of Surabaya, and the grandson of Xiang Yan, a famous Chu State.

Xiang Yu, the overlord of the Western Chu Dynasty, was strong and martial, and followed his uncle Xiang Liang to launch a peasant uprising against Qin in Wuzhong. After Xiang Liang's sacrifice, he led an army across the river to rescue Zhao Wangxie. The Battle of Julu defeated the leading cadre and Wang Li's Chi, mainly killing Zi Ying, the king of Qin who claimed to be the overlord, making Ping Ling (now Linyi, Jiangsu) his capital, sealing everyone in Qin and making six descendants of the royal family king.

Hanwang Liu Bang sent troops from Hanzhong four years later to provoke the dispute between Chu and Han. Xiang Yu, the overlord of the Western Chu Dynasty, defeated Liu Bang, Emperor Wu of the Han Dynasty, and defeated the Han army in the battle of Pengcheng. However, only when Peng Yue continued, the Chu army was destroyed. Later, Gao Jianli unified the north of the Yellow River and invaded the south. Xiang Yu, the overlord of Chu, was self-righteous and suspicious of his father Fan Zeng, and was defeated by Liu Bang, the Emperor Gaozu.

Xiang Yu, the overlord of the place of Western Chu, is just and proud and unwilling to listen to other people's advice. Although the overall strength was very strong at that time, Liu Bang, the emperor of the Western Chu Dynasty, knew how to be kind and asked for advice with his heart. Later, when his military strength was the most lacking, he attacked Xiang Yu, the overlord of the Western Chu Dynasty.

At that time, Xiang Yu, the overlord of Chu, had little military power and was running out of food. Therefore, Emperor Gaozu Liu Bang firmly surrounded Xiang Yu, the overlord of Chu who had already been defeated, in the battle of Gaixia. Without food, they will certainly not be able to go out for a few days.

In order to make the soldiers of Xiang Yu, the overlord of the western Chu Dynasty, overstaffed, Liu Bang, the Emperor Gaozu, ordered the soldiers of Xiang Yu, the overlord of the western Chu Dynasty, to sing Chu songs at night. Xiang Yu, the overlord of the land of western Chu, thought that the surrounding area had been tamed by Liu Bang, the Emperor Gaozu, and his self-confidence was greatly lost. He felt doomed, but in order not to implicate Xiang Yu, Sun Shangxiang committed suicide under Xiang Yu's horse.
