After Cao Cao defeated Yuan Shao to pacify the north, he built a luxurious bronze sparrow terrace in the present position of Handan and invited heroes from all over the world to entertain him. At that time, Cao Zhi, the son of Cao Cao, improvised a poem. Cao Cao was very happy after reading it, and named Cao Zhi the Hou of the Plain. The poem written by Cao Zhi at that time was "Bronze Quetai Fu", but Cao Zhi's "Bronze Quetai Fu" was not a later version of The Romance of Three Kingdoms, and it was precisely because the "Bronze Quetai Fu" was changed by Zhuge Liang in The Romance of Three Kingdoms that people who read the Romance of Three Kingdoms were misled by the poems changed by Zhuge Liang.
Originally, the poem was "What connects the Second Bridge is like shrimp in the sky", but Zhuge Liang changed it to "Take the Southeast of the Second Bridge and enjoy it every day". The original sentence means that the Bronze Pagoda is connected with the East-West Bridge, like a rainbow in the sky, but Zhuge Liang changed it to Cao Cao's intention to hold Er Qiao in his arms and be happy every day. As we all know, Da Qiao and Xiao Qiao are sisters. Da Qiao married Sun Ce, Xiao Qiao married Zhou Yu, and Xiao Qiao was also called "Jiangdong Er Qiao", so Zhou Yu was very angry after seeing Zhuge Liang's revised poem.
Because on the eve of Battle of Red Cliffs, most Wudong people, including Zhou Yu, did not advocate a decisive battle with Cao Cao. In order to arouse Zhou Yu's determination to attack Cao Cao, Zhuge Liang sang this song "Ode to a Bronze Quetai" instead, which successfully angered Zhou Yu and led to Battle of Red Cliffs. Cao Cao also changed the revised version of Ode to a Bronze Quetai from a lean generation to a sly and immoral image. It must be said that The Romance of the Three Kingdoms really misled many people. Moreover, Battle of Red Cliffs occurred before Cao Cao built the Bronze Quetai, and this poem did not appear at that time, so this bridge was invented by Luo Guanzhong.
