What is the fourth day of March?

The fourth day of March is the Cold Food Festival. The Cold Food Festival is a traditional festival in China, after the summer solstice and one or two days before Tomb-Sweeping Day. When the first day of the day is a holiday, smoking is forbidden and only cold food is eaten. In the development of later generations, the customs of sweeping, climbing, swinging, cuju, crochet and cockfighting were gradually increased. Cold Food Festival is the only traditional festival of Han nationality named after food customs.

Cold food festival allusions:

During the Spring and Autumn Period, Zhong Er, the son of the State of Jin, lived in exile in a foreign country for 19 years in order to avoid disaster. Minister Jiexiu is consistent and never gives up. Even "cutting stocks." Zhong Er tried to become a famous gentleman "Jin Wengong". But meson tui didn't want to make a fortune, so he lived in seclusion with his mother in Mianshan. Jin Wengong ordered the release of Yamakaji to force him out of the mountain, but meson was determined not to go out of the mountain and eventually died in a fire.

Jin Wengong remembered his loyalty, buried him in Mianshan, built a shrine and a temple, and ordered the prohibition of cold food on the day of Jiexiu to express his grief. This is the origin of the "Cold Food Festival".
