As mentioned already,
"shi" means gentleman, scholar, soldier,
knight, samurai. Pinyin is shi4.
This is a rich term for Confucian culture,
with at least equal emphasis on scholar
and gentleman (poet?) as soldier.
In Chinese shi4-bing1 is a soldier.
For East Asian computer types,
the Unicode for the character is 58EB.
As an aside, the Kanji title in the
trailer for the coming Tom Cruise film
"Last Samurai" is "Bushido."
