Let's be a bit more specific, shall we? Ship = "ten" (10), using the Sino-Korean word. Ja = "character" as in HanJa, or what people usually regard as Chinese Characters Therefore, ship ja means the Asian character for ten (10), which happens to be: 十 This should make it obvious that the term ship ja as used in this context means the four directions the character is "pointing" to (same as N-E-S-W compass coordinates). This is why its called ship ja mahk ki lol
