According to the reflection of the Three Kingdoms, Cao Cao didn't really want the second bridge, which should be the second bridge, but it was not after Battle of Red Cliffs as the landlord said, but in the fifteenth year of Jian 'an, Cao Cao defeated Yuan Shaosan, conquered the northern Wuhuan and pacified the north. So Ye Jian was built as the capital, and a bronze sparrow terrace was built on the bank of Zhanghe River. It is ten feet high and divided into three groups, each group is 60 steps apart, and the flying bridge in the middle is connected. After the completion of Tongquetai, Cao Cao called a hundred officials of civil and military forces to hold a contest meeting in front of the stage, and ordered his sons to come to the stage to offer gifts. Among them, Cao Zhi wrote a chapter and made this work.

As for your question, before the Romance of the Three Kingdoms, Du Mu wrote "Tongquetai Spring Locks Er Qiao" because some sporadic fragments of the story of the Three Kingdoms have been circulated among the people. Storytellers have used materials for a long time, and the content is getting richer and richer, and the characters are getting fuller and fuller. Finally, many independent stories gradually combined and grew into a masterpiece. These isolated stories have been passed down from mouth to mouth in the society for a long time, and finally they were processed and compiled into a book, which became China's first novel. This is an amazing romance of the Three Kingdoms created by the collective, but Luo Guanzhong just arranged and arranged it, that is, from the beginning of the story of the Three Kingdoms, countless stories of the Three Kingdoms were circulated among the people. It is very likely that the Second Bridge in Bronze Que Fu in the Tang Dynasty was tampered with by the people, and Luo Guanzhong later added Cao Cao's words according to these folk stories.
