墨 (mò): アブラ。for メキシコ [Mo 4 xi 1 ge 1]

The new Chinese teacher in our class has the surname Mo, and he writes characters especially beautifully.

My classmate asked me the name of that doctor whose surname is Mo; I only remember that everyone calls him Doctor Mo.

On the library's list of borrowers, I saw that Mo Xiaoming had checked out three books about Chinese history.
