I had been watching an interview with Jon Huntsman, the former U.S. Ambassador to China, and he was exhibiting his Mandarin fluency on television. In the interview, he said he had a "Chinese name" (Hóng Bópéi), but I'm curious how exactly he came to that conclusion. How does one determine a name if they're a foreigner? Is it something given to them, chosen by themselves, or something else?
