Burn one's bridges refers to the Battle of Julu, which was a major decisive battle in Julu (now Pingxiang County, Xingtai City) led by Xiang Yu (later warlords and rebels from all walks of life also took part in the war) and Wang Li, a famous Qin national, with 400,000 as the main force. This is also one of the famous battles in the history of China.
Burn one's bridges refers to the battle of the giant deer, which is a war in the great uprising at the end of Qin Dynasty. Xiang Yu led tens of thousands of Chu troops (later governors and rebels also took part in the war), and together with Qin Ming and Wang Li, he led 400,000 troops to battle in Julu (now Pingxiang County, Xingtai City), which was also one of the most famous battles in China history.
After the two generals crossed the river, they won a small victory in the first battle. Zhao Jiang Chen Yu urged the invasion. Then, Xiang Yu led the whole army to cross the Yellow River (allegedly to get water), ordered the whole army to burn down houses and tents, and brought only three rations to show their determination to die. With lightning speed, he directly took the giant deer, defeated the tunnel guards, cut off the king's provision route, and surrounded the king from the army.
Xiang Yu's determination and courage greatly inspired the soldiers. The Chu army surrounded Wang Li's army and the morale was high. One is ten years old, and the more he fights, the braver he becomes. After nine fierce battles, he was finally beaten back, Wang Li was captured alive, and Su Jiao, the general of Qin State, was killed. Other Qin Jun soldiers were killed and escaped, and Qin Jun besieged the giant deer and collapsed.
