Story:
In the late Qin Dynasty, General Zhang Han led his troops to attack the State of Zhao. The Zhao army was utterly defeated and retreated to Julu to defend staunchly, awaiting reinforcements.
However, all the other anti-Qin forces remained motionless. Only Xiang Yu led his army to besiege the Qin forces.
Xiang Yu, with his immense strength, capable of lifting a cauldron, charged into the enemy formation, killed the Qin general Su Jiao, and soundly defeated the Qin army.
After the Battle of Julu, which annihilated the main Qin forces, those who had originally stood by and watched began to pledge their allegiance.
