Analysis:
There is a mountain named Mianshan in Jiexiu. According to legend, Zhong Er, the son of the State of Jin, took the courtiers and mesons to flee to the state of Qin, and later Zhong Er returned to China and succeeded to the throne. He forgot to enfeoffment mesons, who lived in seclusion in Mianshan, and Zhong Er forced mesons to push them out of the mountain, and the fire burned Mianshan. Mesons would rather die than leave the mountain and were burned to death in Mianshan. Later, it was named Jiexiu to commemorate this place.
