During the Warring States Period, the Prince of Yan sent a famous assassinator Jing Ke to kill the King of Qin.
Jing Ke, together with the warrior Qing Wuyang, left for Qin with the head of Fan Wuqi, a defector of Qin and the map of Dukang, the most fertile land of Yan.
Approaching the River Yi, Jing Ke sung a heartbroken song impassionedly, "The River Yi is cold as the wind blows, the hero will never return after this departure."
