The origin of Mid-Autumn Festival, Spring Festival, Lantern Festival, Tomb-Sweeping Day, Dragon Boat Festival and Double Ninth Festival.

Origin of Mid-Autumn Festival: The celebration of Mid-Autumn Festival originated from ancient people's sacrifice to the moon, which is the legacy and derivative of China people's custom of offering sacrifices to the moon. Sacrificing to the moon is a very old custom in China. In fact, it was a sacrificial activity of ancestors in some places in ancient China.

The origin of the Spring Festival: The Spring Festival evolved from praying for the New Year at the beginning of the year. In ancient times, people held sacrificial activities at the beginning of the new year after the end of farming at the age of one (year) to repay the kindness of the gods and ancestors of heaven and earth and pray for a good year. Although the situation of ancient sacrificial ceremonies is unknown, we can still find some ancient custom relics from later festivals.

Origin of Lantern Festival: The formation of Lantern Festival custom has a long process. According to general data and folklore, the fifteenth day of the first month was paid attention to in the Western Han Dynasty. Emperor Wu of the Han Dynasty worshiped Taiyi in Ganquan Palace on the moonlit night, which was regarded by later generations as the first time to worship God on the fifteenth day of the first month.

The origin of Tomb-Sweeping Day: Tomb-Sweeping Day originated from the ancestral belief and the custom of spring sacrifice in ancient times, which has both natural and humanistic connotations. It is not only a natural solar term, but also a traditional festival. Grave-sweeping and outing are the two major themes of Tomb-Sweeping Day etiquette and customs, and these two traditional themes have been passed down from ancient times to the present in China.

Origin of Dragon Boat Festival: Dragon Boat Festival originated from the worship of astronomical phenomena and evolved from the ancient Dragon Boat Festival. On the midsummer Dragon Boat Festival, the black dragon spent seven nights in the sky, which is the day of the dragonfly. As the fifth poem in The Book of Changes and the Melon says, "The dragon is in the sky".

The origin of the Double Ninth Festival: The Double Ninth Festival originated from the worship of celestial phenomena and evolved from the harvest sacrifice in ancient autumn and season. The number of "Nine" is a positive number in the Book of Changes, and the two positive numbers of "Nine Nine" are heavy, so it is called "Chongyang"; It is also called "Double Ninth Festival", because both the date and the month conform to nine.
