Brief introduction of Tomb-Sweeping Day gas and Tomb-Sweeping Day gas.

1, "Tomb-Sweeping Day" is one of the traditional "eight festivals a year" in China, which is at the turn of mid-spring and late spring fifteen days after the vernal equinox. The most important custom in Tomb-Sweeping Day is to worship ancestors and sweep graves, which is the most important festival. It is called "Three Ghosts Festival" together with the Mid-Autumn Festival on July 15 and the Cold Clothes Festival on July 10/Sunday.

2. "Tomb-Sweeping Day" was originally only one of the 24 solar terms in the lunar calendar, and it only had the function of indicating phenological changes and seasonal changes. Later, after development and integration, it became a festival with rituals such as climbing mountains and sweeping graves.

3. The original time of "Tomb-Sweeping Day" is 1708 days from winter to the future, and it was later set as April 5. Its origin can be traced back to the Zhou Dynasty. Influenced by the sacrificial culture and ancestral culture, "Tomb-Sweeping Day" pays attention to offering sacrifices to ancestors in order to pray for the smooth production and life in the future. This is the biggest festival of ancestor worship in tradition.

4. The custom of "Tomb-Sweeping Day" worshipping ancestors probably originated from "Cold Food Festival". It turns out that "Cold Food Festival" is one or two days earlier than "Tomb-Sweeping Day", and "Tomb-Sweeping Day" is two different festivals. Later, because the festivals were really similar, they merged. "Cold Food Festival" has the custom of offering sacrifices to Jiezi (the hero who helped Jin Wengong ascend to the throne). After living in seclusion, Wen Gong released Yamakaji and burned him alive in order to force him to appear. In memory of him, Jin Wengong offered sacrifices at the Cold Food Festival. Therefore, Tomb-Sweeping Day, which merged with the Cold Food Festival, naturally has the custom of offering sacrifices.
