This sign references Xiang Yu, known as the Hegemon-King of Western Chu, one of history's most tragic military geniuses. After the fall of the Qin Dynasty, he fought Liu Bang (future Emperor of Han) for control of China. Xiang Yu was incredibly strong, reportedly able to lift a bronze cauldron, and won nearly every battle through sheer force and courage.
Yet his reliance on brute strength became his weakness. He refused strategic retreats, dismissed good counsel, and trusted only in his personal prowess. At the Battle of Gaixia, surrounded and outnumbered, he chose suicide over surrender, believing death preferable to the shame of capture.
The poem's reference to 'moving East Mount beyond the North Sea' echoes an impossible task, highlighting how even the mightiest can attempt the unrealistic when pride clouds judgment.
