This festival originates from the early “the Mid-July” harvest autumn to worship ancestors, the birth of “the Mid-July” can be traced back to the ancient ancestor worship and harvest festival. In ancient times, people often placed their blessings on the gods for the harvest of farming. Worship ancestors in spring, summer, autumn and winter, but the “taste of autumn” in early autumn is very important. Autumn is the harvest season, and people hold sacrificial ceremonies to the spirits of their ancestors, offering the season’s good products to the gods first, and then tasting the fruits of these labors and praying for a good harvest in the coming year.
