The Chinese Communist Party (CCP) regards the Communist Youth League (CYL) as a critical and distinctive mass organization that acts as an “assistant” and “reserve army” for the Party. This article uses the analytical concepts of historical institutionalism and critical junctures to discuss the changes in the CYL during the post-Mao period. We focus on two critical junctures: 1982, when the CYL became a route to rapid promotion for cadres, and 2016, after which its cadres had fewer opportunities for promotion and the CYL was pushed back to its original role in youth United Front work. We also find that the CYL has refined its United Front methods to attract talented young people by offering them services. This reflects the efforts of the CCP regime to adapt to circumstances and ensure its survival.
