Y. R. Chao attended Cornell on a Boxer Indemnity scholarship, and wrote a number of playful letters to his American friends after returning to China. This appears appended to the first of his circular "Green Letters", dated Peking, 1921:
Frisco for 3rd time, no emotion for it. Took sight-seeing tour of Chinatown at night. I believe that most Americans in Frisco who are interested in what they think, or purposely represent, to be things Chinese ought to be executed, or at least no-longer-by-me-tabooed-worded. Of course you of Calif, who know me or my like are OK.
