Aerial view of the Ming River, a symbol of Bama, flowing through the fields in Bama Yao Autonomous County, Hechi city, south China's Guangxi Zhuang Autonomous Region, 21 February 2019. Bama Yao Autonomous County is located in northwestern Guangxi Zhuang Autonomous Region. It became a famed "Longevity Village" worldwide in the 1990s. It is home to less than 300 thousand residents, among whom 94 are centenarians by the end of 2014. With the rise in awareness of health maintenance in current days, an increasing number of people came to know residents in Bama have unusual longevity. It is no wonder that the number of tourists grew 26 fold from 2006 to 2014 and for now, there are more than 100 thousand "migratory tourists "migrating between their hometowns and Bama. Just as every coin has two sides, its fame also poses challenges to the daily life of Bama locals. These transient tourists have brought cultures and lifestyles different from that of the Bama locals', resulting in frictionbetween locals and tourists, according to Li Tianxi, deputy head of the Bama Public Security Bureau. "Migratory tourists" are also doing their utmost to integrate into the local community. For instance, Bama International "Migratory Tourist" Association was founded at the end of 2013.The association remains committed to helping migratory tourists, guiding tourists' behavior and protecting Bama's environment and longevity resources. Ming River, a symbol of Bama, flows through the fields. The shape of this river looks like the cursive script of the Chinese Character "Ming".
