Miscellaneous

My Erdős number is 3 (Erdős → Odlyzko → Jarecki → Xu).

Name order: Chinese (as well as Vietnamese, Khmer, Korean, Japanese, and Hungarian) people's names are usually "surname + given name"; however, many Chinese people overseas, including myself, reverse their name order to avoid confusion. That is, my "actual" name is "Xu Jiayu," where "Xu" is the surname and "Jiayu" is the given name. You are welcome to write any of the following: "Jiayu Xu," "Xu Jiayu," and "XU Jiayu."

Name pronunciation.

I enjoy reading and occasionally writing Classical Chinese poems in my spare time. See my writing samples.
