Guangzhou Baiyun International Airport (IATA: CAN, ICAO: ZGGG), formerly known as Canton Civil Airport (White Cloud) or Pai Yuen Airport, was an airport that served Guangzhou, the capital of South Central China's Guangdong province. Originally opened in 1933, it was one of the first civil airports in China, but was closed on 5 August 2004 when all services were transferred to the new airport of the same name, 23 km (14 mi) to the north.
