In the 1970s, the position of Chinese president was abolished, but Mao Zedong and Hua Guofeng were Chairman of the Chinese Communist Party successively. With the introduction of the Boeing 747, officials started using the CAAC Boeing 747SP for international trips. After the CAAC was split up into six in 1988, the 747s were handed over to Air China, and officials continued using 747SPs under the CA livery.
