Don't break, don't break, then stand at the source.

In the battle of Julu, Xiang Yu often said, "Burn your bridges, or you will die."

"Historical Records of Xiang Yu's Biography": "When Xiang Yu learned that he led his troops to cross the river, they all sank, broke the cauldron, burned the house, and gave three meals to show that his soldiers would die, and there was no return." ?

It means the same as cross the rubicon. There is no turning back, only progress, no turning back.

After Zhang Han defeated Xiang Liang, he thought that Chu soldiers were not a worry, so he led the army to cross the Yellow River and defeated Zhao. The prince of Zhao took Chen Yu as the general and Zhang Er as the phase, and defeated the stag. Zhang Han led the king away and involved 400,000 people to besiege the stag. ?

When Chu Huaiwang heard that Xiang Liang had died, he was very scared. He rushed to Pengcheng from Xu Xu [xū] station, incorporated the troops of Xiang Yu and Lv Chen into his own command, appointed Lv Chen as Stuart, Lv Chen's father Lv Qing as Lingyin, and appointed Liu Bang as county magistrate, Wu 'an Hou, who was still in charge of the party and county army. ?

In the third year of Qin Ershi (207 BC), Chu Huaiwang took Yi Song as the upper general, named Xiang Yu as the last general, and took Fan Zeng as the commander in chief, and led the troops to save Zhao with 50,000 troops. Song Yijun arrived in Anyang, stayed for 46 days and stopped marching.

Xiang Yu suggested to Yi Song: "Qin Jun surrounded the Zhao Yu Julu, so we can quickly lead the troops to cross the river and attack the domestic and foreign Zhao soldiers, which is bound to break Qin Jun", but he refused to send troops and still drank and enjoyed himself in the army. The weather is cold, it is raining heavily, and the foot soldiers are cold and hungry.

Seeing this, Xiang Yu went to see Yi Song in the morning and killed him. Xiang Yu held his head and told the soldiers: "I wanted to plot with Qi, and secretly ordered me to kill him." The generals gave in because of fear and dared not resist, so they pushed Xiang Yu to be a general for the time being. Huan Chu reported this matter to Chu Huaiwang, and Chu Huaiwang appointed Xiang Yu as the general. ?

After Xiang Yu was killed, he was famous as a warlord in Chu State, so he sent Dangyang Jun and General Pu to lead twenty thousand foot soldiers to cross the river, and repeatedly attacked the tunnel that delivered food to Wang Lijun, but the harvest was not great. Zhao sent someone to ask Xiang Yu to send his troops. Xiang Yu led his troops across the river and fought Qin Jun nine times. Zhang Han broke through, and Xiang Yu continued to attack Wang Li from the north with a great army.

After the Chu soldiers beat back Zhang Han, the vassal army was greatly encouraged and attacked Wang Li with Xiang Yu, killing Su Jiao and taking Wang Li alive. Qin Jiang was unwilling to surrender and committed suicide. After the annihilation of Qin Jun, Xiang Yu summoned the governors and generals in Yuanmen, and all the generals knelt down, afraid to look up at Xiang Yu. So Xiang Yu became a vassal general, and all the vassals joined him. ?

Xiang Yu asked the general Pu to lead the troops, crossing the Sanhujin day and night, fighting with him and defeating him. Then Xiang Yu led the whole army and wiped out Qin Jun in the sewage. Zhang Han sent someone to see Xiang Yu again, hoping to conclude a peace treaty. Xiang Yu called military officials to discuss and said, "Now there is less and less military food, so I have to promise them." Military officials said yes.

So, Xiang Yu and Zhang Han met in Huanshui Nanyin and made a covenant. After seeing Xiang Yu, Zhang Han cried and confided Zhao Gao's behavior to Xiang Yu. Therefore, Xiang Yu named Zhang Han King Yong and Sima Xin General, and led Qin Jun to Xin 'an.

Historical Records began to spread with the efforts of Yang Yun, the grandson of Sima Qian, but it was incomplete by the Eastern Han Dynasty.

This edition of Historical Records has 130 volumes, and the number of articles is consistent with what Sima Qian said in the preface. The biography of Sima Qian in Han Dynasty says that "ten articles are missing, and there are notes but no books". There are seven historical books after the relocation, namely, After the Death of Jingji, Wuji, Li Shu and Le Shu, The Book of War (namely, the Book of Laws), Chronology of Generals since Han Dynasty, Biography of Japanese People and Above Three Kings. Liu Zhiji thinks that there are not only two schools, Chu and Feng, but as many as fifteen schools, which supplement Historical Records.

There are two historical records, one is in Sima Qian's workplace (court); The copy is at home. During the period of Emperor Xuan Di of the Han Dynasty, Yang Yun, the grandson of Sima Qian, began to spread the contents of the book to the society, but the length was not much, and it was soon stopped because of the murder of Yang Yun.

The Historical Records created by Sima Qian spread widely, probably after the mid-Eastern Han Dynasty. The Eastern Han Dynasty court also abridged and supplemented the historical records. According to Yang Zhongchuan, Yang Zhong was ordered to delete more than 100,000 words from Taishi Gongshu. It shows that the royal family in the Eastern Han Dynasty is still unwilling to disclose all the historical records, and only let Yang finally abridge them into more than 100,000 words for publication. The Historical Records, with a short span of more than 100,000 words, was lost after the Han Dynasty and has been passed down to this day.
