During the Spring and Autumn Period, there was a beloved princess named Li Ji in Jin Xiangong, Jin State. This Li Ji wanted her son Xi to be a prince, so she framed the then Prince Shen Sheng. Jin Xiangong's other two sons, Yiwu and Zhong Er, fled the State of Jin when things went bad. At that time, many loyal ministers and sages fled with them. One of Zhong Er's followers is called meson push.

Because meson push refused to be rewarded, he once wrote a poem: there are dragonflies in the world. Five snakes follow it, Tamenojo assists. The dragon betrayed his hometown and got his place. Four snakes followed around and got the rain and dew of the dragon. A snake died of shame in nakano.

Someone complained for him, so he dedicated this poem to Zhong Er. After seeing this poem, Zhong Er remembered his promise and regretted his ingratitude, so he personally took people to Mianshan to find Jiezitui. However, Mianshan Mountain winds for dozens of miles, with overlapping mountains and deep forest valleys, which can't be found at the moment. Zhong Er was eager to find someone, so someone gave him a bad idea and set fire to three sides of the mountain. The meson couldn't stand it and would naturally run out from the other side. Zhong Er listened to this idea and ordered the release of Yamakaji. The fire burned for three days and nights before it stopped, but the meson push never came out.
