I'm curious. How would you translate it?
Well, from what I have read it is a foot raised...so it is not clear if the foot is going up, or going down, advancing or retreating...it is in a position to do any of these. Then there is the staff, spear, or halberd...also not specific, but from what I have read / learned it is "stop spear."
Added note....so the spear is not advancing or retreating, it stops.
