The iron is not for sale,

Learn from the past.

East wind is not convenient for Zhou Lang,

Bronze sparrow lock Er Qiao Spring.

Distinguish and appreciate

Du Mu had been to Chibiji, Huangzhou, during his tenure as the secretariat of Huangzhou in the second year of Huichang (842). Standing on the bank of the great river, looking at Chibi from afar, thinking about history, recalling that the Wu-Shu allied forces defeated Cao Bing in Chibi, Ezhou, during the Three Kingdoms period, thus commemorating the "Battle of Red Cliffs" where the three countries stood in the balance. Looking back, I was so excited that I wrote this famous epic.

In the first and second sentences, the writer was in the sand by the river, and the poet put a halberd at the end of the poem, which triggered the historical discussion of the latter two sentences and had a sense of historical depth. Three or four sentences mean that Zhou Yu's victory was caused by chance, and relying solely on temporary luck is not a national policy. If it weren't for the sudden attack of the east wind and the help of the Shu army, Zhou Yu's fire attack plan would show great strength, and then the Wu Dong regime would be destroyed by Cao Cao. These two poems are quite historical and original. The poet's banter about Zhou Yu implies an affirmation of Cao Cao.

Poets are interested in things and eulogize history, pointing out that Battle of Red Cliffs is related to the survival of the country and the safety of society; At the same time, it implies that you are ambitious and will not be reused. See the big from the small.

Broken paintings and heavy sand have not melted so far. Pick it up and grind it, and you can still vaguely see the sword shadow of history. If the east wind doesn't come, how can Zhou Yu use the east wind to burn Cao Cao's 800 thousand water army and win a great victory? The overall situation of the three countries is uncertain. Presumably, when Cao Cao built a bronze sparrow terrace in Yedu (now Linzhang County, Hebei Province) two years later, Wu Dong beauties Da Qiao (Mrs. Sun Ce) and Xiao Qiao (Mrs. Zhou Yu) may be locked in a bronze sparrow terrace, and they have infinite love for spring.
