Why did meson push burn to death in the bamboo forest?

According to legend, this custom originated from the promotion of the introduction of the Jin State when it commemorates the Spring and Autumn Period (surname introduction promotion, also known as introduction promotion, is a function word, and the son is a respectful name). At that time, Jie Zhitui and Jin Wengong Zhong Er were exiled to other countries, and they cut meat for Wen Gong to satisfy their hunger. After Wen Gong restored the country, he refused to make a profit and retired from Mianshan with his mother. Duke Wen burned the mountain for it, refused to go out of the mountain, and clung to the tree. Duke Wen buried the body in Mianshan, built a shrine and a temple, and ordered the son to ban fire and cold on the day of his death as a sign of mourning, which later became a custom. Bamboo represents nobility.
