Guyuan Liupanshan Airport — Guyuan (Yuanzhou), China

GYU denotes Guyuan Liupanshan Airport, serving Guyuan in Ningxia Hui Autonomous Region, China, named after the nearby Liupan Mountains. The airport connects this relatively isolated, ethnically diverse region to larger Chinese cities, supporting both local residents and tourism to Liupanshan's scenic and historically significant sites, including locations tied to the Chinese Communist Party's Long March history. GYU represents part of China's broader push to extend aviation access into its less-developed northwestern interior, reducing dependence on long overland journeys through Ningxia's mountainous and arid terrain. Traffic is modest but steadily supports regional economic and administrative connectivity.
