During the Spring and Autumn Period, Prince Zhong Er went hungry during his exile. Jiezitui cut a piece of meat from his thigh and cooked the broth for the prince to drink. Zhong Er regained his spirits. He shed tears when he found the source of the meat.

Later, Zhong Er became a monarch and rewarded his ministers, but he only forgot the meson push. Many people complained about meson push, but meson push quietly went to Mianshan with his mother.

When Jin Wengong Zhong Er heard about it, he personally took someone to ask meson to push it, but the mountain was too high to find, so someone proposed burning Mianshan and forcing meson to push it out. The fire burned all over Mianshan, but there was no trace of meson push. After the fire was put out, people found that Jiezitui had died sitting under a tree, leaving a bloody book "May the master be clear forever". Jin Wengong was very sad to see him.

In order to commemorate Jientui, Jin Wengong ordered the whole country not to light a fire, but to eat cold food, which is the so-called "Cold Food Festival".
