Tomb-Sweeping Day, also known as the Cold Food Festival. According to historical records, during the Spring and Autumn Period, Zhong Er, the son of the State of Jin, fled into exile in other countries for 19 years, and the minister Jiezitui always followed around and never gave up; Even "cutting stocks".

Zhong Er made great efforts to become a generation of famous monarch "Jin Wengong". However, Meson Tui did not want to get rich, so he retired to Mianshan with his mother. Jin Wengong ordered Yamakaji to be released in order to force him out of the mountain, but Meson Tui was determined not to go out of the mountain and eventually died of fire.

Jin Wengong, mindful of his ambition to be a loyal minister, buried him in Mianshan, built a shrine and built a temple, and ordered a ban on fire and cold food on the day of Jietui's death, in order to express his grief. This is the origin of the "Cold Food Festival".
