Daxin County is under the jurisdiction of Nanning City, Guangxi Zhuang Autonomous Region, and shares over 40 kilometers of its southern border with Vietnam. Formerly an undeveloped area, it is famous for its Detian Scenic Zone, which boasts a variety of fantastic landscapes. Along with the enhancement of friendly ties between China and Vietnam, the Detian Scenic Zone was established several years ago, and was so named for its spectacular Detian Waterfall.
