Before Xi, a pathway for future leaders had begun to form, where an heir-apparent took on a Standing Committee position and the vice presidency five years before they were appointed to the top job. Both Xi and his predecessor, Hu Jintao, ascended in this manner.
But that precedent, too, was broken when no officials young enough to serve three terms made the Politburo Standing Committee in 2017. Analysts tracking Chinese politics warn against expecting an anointed successor this year either, arguing that Xi’s extended rule could bypass entirely the generation that will dominate the 370-odd full and alternate members of the Central Committee (the body below the Politburo) over the next 10 years.
This article names some possible people to watch, who I'll add here.
@BTE This is Xi's daughter and only child and he protects her fiercely. She is clearly preparing for a career in politics IMO.
