Tonghua Sanyuanpu Airport — Tonghua, China

Tonghua Sanyuanpu Airport serves the city of Tonghua in Jilin province, northeastern China, a region known for its mountainous terrain, ginseng cultivation, and proximity to the North Korean border. TNH connects Tonghua to major Chinese cities such as Beijing and Shanghai, supporting both business travel tied to local industry and tourism to nearby Changbai Mountain natural attractions. The airport's development reflects broader efforts to improve air connectivity across China's less accessible northeastern provinces, where winter weather and rugged geography can make ground transportation slower and less reliable. Tonghua's historical significance in Chinese industrial and revolutionary history adds further context to the airport's regional role.
