Interestingly, and this will also undoubtedly surprise foreign readers, he lists oversight by "other political parties, the judiciary, the public, and the media" as part of the system of self-reform, all part of a “constructive and mutually reinforcing interaction between supervision by self and by others.” We always assume that the Communist Party of China abhors external scrutiny and here you have Xi Jinping himself telling the Party leadership that it’s not just useful, something they must “readily accept,” but historically decisive - an essential component of one of only two answers, across millennia of Chinese history, to the question that brought down every historical Chinese dynasty. That, overall, is Xi's answer to the question of legitimacy: self-cultivation itself. Not self-cultivation as a path to legitimacy, but self-cultivation as legitimacy. The way a healthy body isn't rewarded with health: it simply is healthy.
