This bridge was built in the early years of Hongwu in Ming Dynasty. Phoenix people who believe in geomantic omen say that the bridge cut the neck of a dragon and made it beheaded. Zhu Yuanzhang, an Anhui boy born as a monk, is the culprit. He listened to the rumors of the division of Yin and Yang, set out from Kunlun Mountain to pursue a Long Mai, and came to Wuzhai Sicheng via Yunnan-Guizhou Plateau. He said that the southern suburb of Nanhuashan, which has an extraordinary momentum, is in the same strain as Qifeng Mountain and plunged into Tuojiang River, which is the leader he is looking for. It is inferred that one day someone will come out of this place and win the Central Plains, and the only thrill will come out. How could Emperor Zhu allow the distant Phoenix to have his potential enemies? So Zhu Bi hooked up, the dragon neck was cut, the phoenix feng shui was destroyed, and the phoenix could never get out of the emperor again.
