The Hani Four Seasons Production Tune is spread in the Hani settlements in Honghe, Yuanyang, Luchun, Jinping, Jianshui and other counties in Honghe Hani and Yi Autonomous Prefecture, Yunnan Province. The lower limit of its origin is no later than the Tang Dynasty. As an encyclopedia of mountain terrace production technology and its etiquette and taboos, the Hani Four Seasons Production Tune includes five units: introduction, winter, spring, summer and autumn. The introduction emphasizes the significance of the Four Seasons Production Tune passed down by the ancestors to the survival of the Hani people. The rest of the part tells the procedures and technical essentials of terrace farming in seasonal order, as well as the corresponding astronomical calendar knowledge, natural phenological change laws, festival and sacrificial knowledge and life etiquette norms. The Four Seasons Production Tune has a strict system, is easy to understand, can be recited and sung, and has lively language. It is close to production and life, and has a long history of inheritance and has a broad mass base. It is not only a comprehensive summary of terrace production technology, but also a culmination of the social ethics and moral norms of the Hani people. The Four Seasons Production Tune has witnessed the evolution of the Hani rice terrace civilization and has important reference value for the study of the historical and scientific value of human rice terrace civilization. At the same time, its straightforward, simple and humorous language expression style gives people a warm and touching artistic enjoyment and aesthetic experience. Whether in the past or now, the Four Seasons Production Tune, which is passed down orally and by heart, plays a guiding role in the production and life of the Hani society. With the changes in society and the advent of the wave of economic globalization, especially with the influx of foreign strong cultures, the values of young Hani people have changed, and the inheritance of the Four Seasons Production Tune of the Hani people has become a lack of successors. At present, there are only a handful of elder artists and priests who can systematically sing the Four Seasons Production Tune, and the young generation of Hani people who devote themselves to learning the Four Seasons Production Tune are rare. The rescue and protection of the Four Seasons Production Tune is imminent. (No pictures yet, welcome to provide.) (No pictures yet, welcome to provide.)
