It's kind of funny how people who have made it as big as Jack Ma are still obsessed enough with Harvard to mention almost as a badge of honor that they were rejected from Harvard. As if to say "see Harvard was obviously wrong here". Harvard or any top school in no way can accept anywhere near all of the applicants that are qualified to attend those schools. As such there will be people that will be rejected and accepted almost arbitrarily at the whims of the admissions staff and or quotas of one type or another.
