jiang shi in Cantonese is goeng si and gangshi in Korean, but in Chinese it's still jiāngshī (僵尸 or 殭屍).
googled it, and geung si seems to be in the title of a.. probably.. seems to be.. a famous jiang shi movie...? "Geung si sin sang" or "Mr. Vampire" http://www.hollywoodreporter.com/review/rigor-mortis-geung-si-film-617719 http://www.imdb.com/title/tt0089371/ if I remember it right, it's the source of the popularly used writing on Yoshika's charm (since originally Yoshika's charm is at an angle where the player can't see the writing)
