How to choose strategies of handing traditional culture down is an unavoidable subject in the new situation. The author of the article thinks that clothing, which is believed to be the visiting card of a people, should be simple with symbolization, pictorialization, totems and commercialization. Handing down of the living culture should be combined with ecosystem environments and places of interest to develop its content step by step. One cultural item should be exploited in one place to keep it alive forever. We should make good use of educational, research and translating organizations, media and the Internet to propagandize old and new characters and works. Some museums should be built up to protect metallic and stone relics. Setting up ecological museums or cultural villages and parks is an effective method. We should find out a new way in which key points about the understanding of the culture are explained clearly, core advantages are developed and cutlural labour force and propaganda work are revived The most important thing is to make complete use of the laws and policies on minority self-rule to find out the best way to keep Yi's traditional culture alive.

作者认为，作为民族身份"名片"的服饰应以简明为原则尽量符号化、图案化、图腾化、商业化；作为活文化的仪式与习俗的传承，除了在经济发展的前提下以村寨为基本单位尽量保护和弘扬，要尽可能与生态环境和旅游胜地紧密结合进行单个文化主题的念珠式贯串开发，一地深入开掘一个文化内蕴，使之可以传之久远；依托教育、科研、翻译机构和文艺传媒、互联网传承新老文字及典籍文化，建立文博场馆保护金石文物；建立民族生态博物馆或民族文化村文化园等也不失为一种有效的方式；译解文化传承基因，培育核心发展优势，形成文化再生力传播力，是一条应该认真探索的道路；最重要的是要充分利用好民族区域自治政策法规，使之发挥的效益最大化，并从法律和政策上寻求最佳的传统文化传承策略。
