Abstract:As an important part of the spiritual wealth of the Yi nationality, Yi people's folktales have expressed the aspiration for a better life and the yearning for truth, goodness and beauty. Until now, the Yi people's folktales still have positive thinking and unique cultural value. Yi people's folktales are the treasure house of improving the quality of public morality, the classical textbooks of inheriting national history and culture, the spiritual nutrition of cultivating public sentiment, the valuable reference to improve the level of artistic creation, and the deep soil of promoting the development of national culture industry. As a non-renewable and intangible cultural heritage, the Yi people's folktales have important and profound research value.
