In the horizon of nontraditional security cultural safety nowadays is one of important and difficult problems facing the world. It will greatly influence national continuity, national sovereignty and social system. Yunnan, a border province with the most cross-border ethnic groups in China, has generally complicated and sensitive social and cultural problems, which has strategic significance in the aspect of cultural safety. Taking the Bulang nationality in Xishuangbanna in Yunnan as a case, the paper focuses on the study of the survival and continuity status of the state-level intangible cultural heritage, Bulang Nationality's Singing and Instrument Playing. The research study discovers some challenges in its related cultural security including weak culture survival and continuity because of lack of the traditional culture identity, unsustainable development ability due to insufficient funds, a dwindling breed of inheritors causing inheritance chain unsustainable and a noticeable impact on the national identity by cross-border exchanges. As a consequence, this study suggests in the view of cultural security vision that the protection and adaptation of the traditional ethnic culture should deal with inside-outside relations, old and new relations and the relations between differences and similarities.
