This poem is about Jing Ke stabbing the king of Qin. Killing the king of Qin is a mortal task. Jing Ke will surely die in the state of Qin, and Prince Dan of Yan will be sent to Jing Ke by Yishui. "The wind blows and the water cools, and the strong men will never return" is also the allusion.

When seeing off his friend in Xiao, he couldn't help thinking of the scene where a strong man Jing Ke set out from here to assassinate the king of Qin, so he wrote this poem. Although Jing Ke died, Xiao remained cold, as if telling Jing Ke's lofty aspirations, full of infinite reverence for him, which made people respect him.

Luo, the top four heroes of Kang. "Send someone away in Yishui" was written before the anti-empress Wu Zetian. The poem borrowed ancient lyrics and expressed his lofty heart and deep depression.

Yishui: It's in Yixian County in the north of Hebei Province. During the Warring States Period, Jing Ke, a chivalrous man, was entrusted by Prince Dan of Yan State (yan dan in the poem) to go to Qin State to stab Ying Zheng, the king of Qin (Qin Shihuang after the unification of China). When he left, Yan Dan and others went to Xiao to see him off. Jing Ke sang the song "The wind blows and the water cools, and a strong man is gone forever" to bid farewell to everyone. Later, he was killed for trying to assassinate the king of Qin.

A strong man takes the crown: a strong man refers to Jing Ke; Hair rushing to the crown, that is, anger rushing to the crown, anger is so high that the hat is propped up by hair, describing it as very angry.

Translation:

Think that year, Jing Ke and Yan Taizi Dan bid farewell here, and strong men were indignant. The former chivalrous man is gone, and Xiao is still so cold today.
