回複：今天和我導師聊，說北大隻要美國Harvard,Johns Hopkins畢業的海龜。

Understandable for accepting Haigui from Harvard. But John Hopkins is not that great either to be named here. The reason to name JP, may be because the engineering dean in PU was a department chair from John Hopkins. But actually, he got his own PhD from PU, not from John Hopkins.
