After Li Zicheng's chief strategist was captured, he spoke to the Qing army and was released.

The chief strategist told the Qing army that he was a fortune teller. Because the Manchu people believed in divination, they released the chief strategist who called himself a fortune teller. Li Zicheng was a famous military general in the late Ming and early Qing Dynasties. In the later period, Li Zicheng also established Dashun Dynasty, but this Dashun Dynasty didn't last long before it was defeated by Manchu fighters. Although Li Zicheng himself has a good military talent, it is impossible for him to establish the Dashun Dynasty without the help of his chief strategist.

His chief strategist's name is Song Xiance. From this name, we can see that Li Zicheng is definitely a good strategist. When following Li Zicheng, Song Xiance put forward effective strategies for Li Zicheng. Although Li Zicheng established the Dashun Dynasty through the stratagem of Song Xiance, generally speaking, the Dashun Dynasty at that time did not have the power to resist the Manchu Dynasty.

In the battle with the Qing Dynasty, Li Zicheng's army gradually fell into decline. At the beginning, Li Zicheng was forced to retreat from the capital by Manchu soldiers. 1645, Li Zicheng was killed in Tongcheng county, Hubei province. From then on, the Dashun Dynasty was declared dead, and Song Xiance, who followed Li Zicheng, was also captured by Manchu soldiers.

When asked, Song Xiance had a brainwave and told Manchu soldiers that he was a fortune teller. Hearing that he was a fortune-teller, Manchu soldiers let him go. At that time, Manchu people were still willing to believe in divination. They believe that divination can bring them good luck to some extent. Because of this, Song Xiance, a child prodigy, lied that he was a fortune teller, thus escaping the embarrassing situation of being a prisoner.
