I try to look up your compositions when I think it's a Chinese character, that
way I improve my Chinese and chess program at the same time :) ... see:
http://zhongwen.com/zi.htm
On the left side you can click on all the characters to get some explanation,
for example your last Chinese mate problem was the character for "official" or
"minister", called CHEN2 in Chinese if I'm correct.
This one however isn't clickable ... it's the 5th character with a black
background on the page above, now that should have told me something, hèhè!
