What kind of poem is Red Cliff?

This is an epic poem by the poet Du Mu. And it's a seven-character quatrain. The author lamented that there were opportunities for heroes to become famous in history, but they were born at the wrong time and failed to display their talents. The author believes that as long as there is an opportunity, I believe I will always make a difference. Red Cliff borrows the stories of Zhou Yu and Cao Cao, expressing the frustration of poets and heroes. The creative background of Chibi:

This poem was written by the poet after passing through the famous ancient battlefield Chibi (now Chiji Mountain in the southwest of Wuchang County, Hubei Province) and feeling the success or failure of heroes in the Three Kingdoms period. Battle of Red Cliffs, which took place in October of the 13th year of Jian 'an (2008) of Emperor Xian of Han Dynasty, was a major battle that played a decisive role in the historical situation of the Three Kingdoms.

As a result, Sun and Liu were defeated, and Zhou Yu, the 34-year-old commander-in-chief of Sun Wu, was the most important person in this battle. The poet watched the remains of the ancient battlefield and expressed his unique views on Battle of Red Cliffs.

Appreciation of the first two sentences in Red Cliff;

"If you don't sell iron, you will recognize it if you wash it." These two sentences mean that the broken Zhan Ji sank in the sand and was not eroded. After grinding, he recognized it as a relic of the previous dynasty. Here, these two descriptions seem dull, but they are uneven. The broken halberd is buried in the sand, pointing out the historical situation here. The broken sand in Zhan Ji has not been eroded, suggesting that time has passed and things have changed.

It was because of the discovery of this rusty "broken halberd" buried at the bottom of the river for more than 600 years that the poet had a lot of thoughts, so he had to grind it out and identify it, and found that it was a weapon left over by Battle of Red Cliffs. In this way, the remains of the former dynasty further aroused the author's imagination and laid a good foundation for the later expression.
