Линь Бяо
Chaos continued throughout China for three years, particularly due to the agitations of the Red Guards until the CCP's ninth congress in 1969, when Lin Biao emerged as the primary military figure, and the presumptive heir to Mao in the party. In the months that followed, Lin Biao restored domestic order, while diplomatic efforts by Zhou Enlai cooled border tensions with the Soviet Union. Lin Biao died under mysterious circumstances in 1971.
