Wuhan Tianhe International Airport (IATA: WUH; ICAO: ZHHH) is located in Huangpi District, approximately 25 kilometers from central Wuhan. The original profile describes it as a 4F-class civil international airport and a major hub in central China serving scheduled international flights and international passenger and cargo movements. The entry also referred to a transit visa policy introduced in January 2019; travelers should consult current official entry requirements rather than rely on this historical project description.
