Yes, you can call me “professor” now (only if you insist).
Today I officially received my certificate of appointment as professor at Beijing Jiaotong University, from the hands of Mr. Li Zhang, Ph.D. and Professor, Associate Dean, School of Economics and Management of the University.

Pictured are also Sun Bin (haha, trying to hide) and Ms. Li Zuo, Associate Professor, Director of International Exchange Center.
I also gave them a copy of my book, “Toxic Capitalism”.
