Tsinghua University? The man you mentioned didn't graduate from Tsinghua, and his current research institute doesn't belong to Tsinghua University.

He graduated from Tsinghua University Medical College with a doctor's degree, and now his research institution is Tsinghua University Medical Center. The research level is not far from the real "Tsinghua Medical Department" in Tsinghua, but there is still a big gap. Pay attention to the words, which may be confusing. I hope I can help you.
