What do you think of the origin of Tomb-Sweeping Day?

Where did this traditional festival in Tomb-Sweeping Day come from? Folklore researchers hold different views.

First, Qingming is because of solar terms. Qingming is one of the twenty-four solar terms in the China lunar calendar. According to the Astronomical Training of Huainanzi written by Liu An in the Western Han Dynasty, on the fifteenth day after the vernal equinox, the bucket refers to oneself for the purpose of Qingming. April 5 of the Gregorian calendar and around March of the lunar calendar; The sun reaches longitude 150. The first day was Tomb-Sweeping Day.

Second, Qingming is the vulgar expression of solar terms. Tomb-Sweeping Day has two meanings, one is solar terms, and the other is festivals. Solar terms are symbols of time series, while festivals contain some customs and commemorative significance. The reason why Tomb-Sweeping Day can evolve into a festival is mainly due to the meson push in the Spring and Autumn Period. The Chronicle of Jingchu records that Jin Wengong and Jiezitui both died, and Zitui cut off his shares in order to satisfy Wengong. writing

The public rejuvenating the country, the son pushing is unique, and the son pushing the song of the dragon and snake. When Wen Gong asked him, he refused to come out. Instead, he burned firewood and pushed it to death. Wen Gong lamented that people were not allowed to make a fire on May 5th. Since then, there has been a cold food festival. In the Qing Dynasty, the Cold Food Festival was similar to Tomb-Sweeping Day, so it was called Tomb-Sweeping Day, which was gradually ignored.

Thirdly, after a long historical evolution, the Qingming Festival formed Tomb-Sweeping Day. According to legend, Dayu celebrated the peace of the world with Qingming after the flood control. When the Zhou Dynasty formulated the calendar and determined the 24 solar terms, it named the March Festival Qingming to mark the Qingming of heaven and earth. The first, fifteenth and twenty-fourth solar terms of Qin and Han dynasties went to the mausoleum to pay homage. In the Tang Dynasty, in the twentieth year of Kaiyuan, Emperor Ming of the Tang Dynasty issued a letter. The old Tang book says that cold food goes to the tomb, and there is no scripture. According to modern legend, sleeping is a custom. Because cold food is similar to Qingming, so cold food and Qingming are both called Tomb-Sweeping Day. Qingming has experienced thousands of years of evolution since ancient times, and has officially become a traditional festival of the Chinese nation. Tomb-Sweeping Day has a long history among Chinese people, but there is no unified understanding of its origin in academic circles.
