Taking the Ritual of Sacrifice to Heaven of the Naxi at Lezhu village as a case stud-y, this article tries to explore how a typical Naxi village handles the relationship between its tradi-tional culture and modernity, and how it reshapes its unique culture in the process of cultural change, and preserves its cultural characteristics. The Ritual of Sacrifice to Heaven is a grand and complicated ceremony of the Naxi. The proce-dure of this ritual at Lezhu village generally in-cludes the following steps: 1 ) planting sacred trees;2 ) offering incense sticks and rices;3 ) offer-ing wine;4 ) cleaning impurities;5 ) offering un-cooked food; 6 ) offering cooked food; 7 ) atoning for the sins and praying for blessings; 8 ) feeding crows and eagles;9) sharing the food. According to the analysis of the author, the revitalization of the Ritual of Sacrifice to Heaven in Lezhu village is related to the following reasons:1 ) the formation of united-groups for sacrifice to heave;2 ) the power of the people’s belief in a small community; 3 ) the effort of folk “enthusi-asts” ;and 4 ) the geographical location of the vil-lage. Concerning the inheritance and change in the Ritual of Sacrifice to Heaven at Lezhu village, we should notice that some traditions have been inheri-ted while some have been changed. In the case of Lijiang , economic factor ( especially tourism indus-try) has played an important role in the ethnic cul-tural change. On one hand, it can accelerate the spreading of the Naxi traditional culture, enhance the Naxi’s ethnic confidence and identity, and cre-ate chances for local economic development, on the other hand, the traditional culture might lose its foundations during the process of spreading and exchanging. Social change can result in the lose of tradi-tional culture, and the Naxi’s Dongba culture in Lijiang plain is facing this problem. A slightly im-proper behavior can lead to the discontinuity, or e-ven disappearance of ethnic traditional culture. There is always a paradox of “center-margin”concerning the economic development and ethnic traditional culture inheritance. Ethnic traditional cultures normally have no enough survival space in the economically developed areas while they are preserved much better in the economically back-ward mountainous areas. To a certain degree, the revitalization of the Naxi’s Ritual of Sacrifice to Heaven at Lezhu village is due to the relatively backward of economics. Following the development of transportation, communication and internet, people’s concept of space and time has changed;modern civilization has strongly impacted the Naxi of Lijiang. The Naxi of Lijiang, like other ethnic minority people in southwest China,are also facing a problem of cultural discontinuity or reshaping of the tradition. We should aware that the society is develo-ping, and cultural change has its inevitability. As a social member, we should ,on one hand, inherit the culture, and on the other hand, understand its change and development.
