Beijing, within the Beijing International Mathematics Center on the Yanbei University campus, Tian Yanzhen glanced at the time after receiving the email forwarded by Xue Song.
It was already five twenty in the afternoon.
But it was still early. There was still an hour until dinner, and since there was nothing much to do today, Tian Yanzhen conveniently downloaded Qiao Yu's paper onto the computer and then printed it out.
Tian Yanzhen had always had an impression of Xue Song. After all, he was once a professor at Princeton, and after returning to Huaxia, he served as vice president at Yanbei University, mainly responsible for foreign affairs.
So he has always maintained contacts with many mathematics professors from Princeton, including Xue Song's mentor Jure Bhalgava.
When Xue Song returned to the country, Jure Bhalgava even talked to Tian Yanzhen about this student.
