Outside the East Gate of Chengdu, Sichuan, there is a Zhenjiang Bridge. It was built for flood control. Not far from the bridge, there is a stone tower called Huilan Tower, which is said to be used to suppress the dragon at the bottom of the water and benefit the people.
At that time, in A.D. 1644, Zhang led the peasant army to establish its own political power in Chengdu, Sichuan, named Daxi, and also transformed the original Shu into its own palace, named Traffic Hall. Once, when Zhang was out, he overheard the children singing a strange nursery rhyme. The bridge is a bow, the tower is an arrow, and the bow points to the hall. In a rage, the tower was demolished, and the stone tablet was discovered after the demolition. Moreover, there is Zhuge Liang's signature on the stone tablet, so it is considered as a prophecy left by Zhuge Liang.
Zhang was even more surprised when he saw it, and then he ordered his men to break the stone tablet. Three years later, the army of the Western Expedition led by Zhang and the Qing Dynasty wiped out the army led by Wang. For the first time, Zhang was unfortunately discovered by Hogg when he was outflanking, and some people said to Hogg that this was the queen mother of the West. Later, Prince Xiao shot an arrow with a strong bow, and an arrow pierced Zhang's chest, and Zhuge Liang's prediction was completely fulfilled.
