State-run Chinese media on Tuesday reported on a social media post from someone claiming to be a former classmate of Ma's, who said that they joined the Communist Party while in university.
"We all joined the party around the second or third year of university. Back then, joining the party meant not just that you were a good student, but also that you had integrity, organizational ability, enthusiasm and idealism," the post said, according to a translation that matched a screenshot of the post seen by CNBC.
