As a fan of online literature, I don't have any real-time updates about the 2019 Yunnan University folklore graduate student reference book. However, the research subjects of folklore were generally the folk traditions, customs, religious beliefs, festivals, and celebrations formed by human society, culture, and history. If you want to study folklore in depth, it is recommended to read relevant classic works such as Introduction to folklore, Research on Chinese Folk Culture, Chinese Traditional Festival Culture, etc. In addition, you can also pay attention to some academic journals on folklore, such as "Folk Studies" and "Chinese Folk Studies", to learn about the latest research results of folklore.
