Ethnic Yi people attach great importance to oral debate activities in their folk life, which creates good conditions for developing the unique oral Kezhi culture, and forms an essential cultural and recreational activity in Yi people''s lives. Yi''s Kezhi advocates core values such as truth-seeking, goodness-pursuing, beauty-loving and progress-striving.It is distinctly oral, knowledge-rich, witty and interesting, performative and entertaining and profoundly educational, and is of great research value for Yi people''s history, culture, literature, art and social harmony. A set of long-term and effective mechanisms need to be established to promote the publicity and research of Yi''s Kezhi for its better inheritance and development.
