He's 71, not young, but not OLD. He's been trying for a decade or two to create a Mao-like personality cult, but between there being many who remember the bad old days of the Cultural Revolution and the insane and oppressive over-reaction to Covid, that effort has failed. I don't think he will be widely mourned, especially not in China's several ethnic-group "autonomous regions" (where being of the pertinent ethnic group means living in oppression and suppression).
