Bama Yao Autonomous County of the Guangxi Zhuang Autonomous Region is located in the sloped zone from the Yunnan-Guizhou Plateau to the Central Guangxi Plain. This area has a tropical monsoon climate and karst landforms. It is featured by “Eighty percent of the land is mountains, ten percent is water body, and the rest ten percent is farmland.” It is a complex area that comprises a key national ecological function zone, a national tourism demonstration zone, a designated poverty alleviation county by the Ministry of Culture and Tourism, and a national key rural revitalization assistance county. Bama is known as a “longevity town in the world, a holy land of Chinese people” because of its special healthful geographical environment and longevity cultural resources

1Healthful geographical environment: comfortable temperature (average 20.4℃), small molecular cluster six ring (70-80 Hz) and weak alkaline (pH 7.5-8.5) water, high air anion (20,000-30,000/cm
3), suitable geomagnetic intensity (approximately 45,500-50,000 nT), far infrared sunlight (4-14 micron wavelength) and selenium-rich soil (>0.4 mg/kg). Longevity health resources: longevity genetics, longevity lifestyle, Zhuangyao medicine resources, ceremony to worship gods and ancestors, and a culture built on respect and filial piety (Tan and Zhou,
2022).). Bama County has explored the special development model of “the steady growth of ‘migratory bird’

3Panyang River Basin: There are wide and narrow aspects of this region. The case study of this article refers to the narrow area of the river basin refers to the area in Bama County, from the cave entrance at Baimo Village to the starting point of Panyang River rafting in Ganshui Village, with a total area of 30 km

There are 6 administrative villages along the river: Poyue Village, Pingan Village, Songji Village, Jiazhuan Village, Baima Village and Lagao Village; all are Zhuang settlements, belonging to Jiazhuan town (rated as the first batch of healthy towns in Guangxi Zhuang Autonomous Region). In addition, Bama refers to natural villages as “tun,” and several “tun” (natural villages) together form an administrative village (Tan and Zhou,
2022).) is rich in longevity health tourism resources, and commercial living resources are the most concentrated in the area (Tan and Xu,
2018) making it the most popular area for “migratory birds.” Due to its healthful geographical environment, low rural living costs, and the community “migratory bird” atmosphere, the Panyang River Basin continues to attract an influx of various types of people and the inflow of multiscale elements, which has led to the renewal of the material landscape and changes to the social space in longevity villages to create diverse, mobile, and heterogeneous communities (Tan and Zhou,
2022). This area thus provides a typical and expandable case to be used by research on GRCD (
