Meanwhile, New Year, Pray in Spring and Return in Autumn not only play significant roles in agricultural production, but also evolve to farming holidays which are enriched with more social connotations. Centered on husbandry and production, some folklore that is rich in local color has been formed in Dong society. The writer introduced some farming ritual of Dong ethnic group, such as, sowing, Kai Yang Men, Rain-praying, Chang Xin, reaping and Lunar New Year, summarized their belief in the land worship, festival ritual, ancestor ritual and ceres ritual. It is concluded that sacrifice is a production-related folklore, which is formed by repeated operation and constant practice. Some taboos were also prohibited in agricultural sacrifice because people were not able to change the unfavorable reality of farming with their insufficient experience and knowledge; however, they resorted to witchcraft for the purpose of harvest. It is believed that the activity of sacrifice will also be kept in the life of Dong ethnic group due to their dependency on agriculture and the land.展开更多
