Cao Cao set up a bronze sparrow terrace to gather beautiful women in the world. Zhuge Liang lied that Cao Cao had attacked Jiangdong for the sake of "Jiangdong Er Qiao". Zhou Yu didn't believe it at first, but Zhuge Liang moved out of Cao Zhi's "Ode to a Bronze Quetai", which contained a sentence: "Take Er Qiao in the southeast and seize the opportunity." . Zhou Yu was flustered after hearing this, because Da Qiao was Sun Ce's wife and Xiao Qiao was Zhou Yu's wife. Zhou Yu showed Zhuge Liang his determination to resist Cao Cao.
Romance of the Three Kingdoms is a romantic novel, which is quite different from the real history. However, Du Mu, a poet in the Tang Dynasty, also wrote a poem: "The east wind will not help Zhou Lang, and the bronze finches will come to Er Qiao in the spring." This poem was definitely written earlier than The Romance of the Three Kingdoms in the Ming Dynasty, which seems to support each other. However, it is not very convincing to say that Cao Cao had wild thoughts about "Jiangdong Er Qiao" when he marched eastward to Jiangdong.
First of all, Cao Cao built Tongquetai in the winter of the fifteenth year of Jian 'an, that is, in 2 10 AD; The "Battle of Red Cliffs" took place in the 13th year of Jian 'an, that is, in 208 AD. Tongquetai is two years later than Battle of Red Cliffs, so there is absolutely no Fu on Tongquetai written by Cao Zhi before Battle of Red Cliffs.
Secondly, some people say that the "second bridge" in Tongquetai Fu refers to two bridges, because in ancient times "bridge" and "Joe" were interlinked, and there is a saying in Tongquetai Fu that "the second bridge is in the east and west, if the sky falls." However, Cao Zhi's Ode to a Tongque Terrace does not contain the above two sentences in Wei Ji's records quoted in the History of the Three Kingdoms.
However, there are these two sentences in Fu on the Stage, which is included in The Three Kingdoms of Qin, Han, Six Dynasties and Three Dynasties. The Chronicles of the Ancient Three Dynasties, Qin and Han Dynasties, Three Kingdoms and Six Dynasties was edited by Yan Kejun of A Qing Dynasty, which was far from the Three Kingdoms period. As for which is right, people have different opinions.
As for Du Mu's Red Cliff, we can understand it this way. After Zhang Xiu surrendered, Cao Cao married his aunt. After capturing Pi, he married Du Fu, the wife of Lu Bu's Qin Dynasty. After entering Yecheng, Cao Pi married Zhen Ji, Yuan's wife. Based on this rule, Du Mu may speculate that if Cao Cao lays the foundation of Jiangdong, the beautiful "Jiangdong Er Qiao" is inevitable. Perhaps it was because of this poem that Luo Guanzhong came up with the idea of inspiring Zhou Yu with Er Qiao.
