Introduction to the Ethnic History Museum: The wing is now used as an exhibition hall, displaying the blue embroidered python robes and black silk satin sixth-grade official court robes awarded by the Qing Dynasty court, exquisite bamboo weaving arts, and rare bay leaves. Sutras, gold and silver ornaments, seals, Dai classics, toast household items and other objects are of great historical and artistic value and provide precious cultural relics and historical materials for the study of local ethnic history.
