How many of the seven xiangqi piece types can move diagonally?
These answers restate the rules implemented by our open-source engine, which follows the WXF laws for movement, checkmate and both repetition rulings: a side that forces a repetition by perpetual check or perpetual chase loses rather than drawing. The chase half has not been validated against the official casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it before publishing.
Direct answer
Two out of the seven types move purely diagonally: the advisor, one point at a time, and the elephant, exactly two points at a time. The general, chariot, cannon and soldier are confined to straight up, down, left and right movement. The horse is the one piece that combines the two, one orthogonal step followed by one diagonal step, in every move it makes.
Why this matters for reading the board
Because diagonal movement is rare in xiangqi, spotting it quickly narrows things down enormously: any diagonal threat on the board can only be coming from an advisor or an elephant, both of which are themselves confined to a small, fixed set of points. A newer player scanning for danger can usually rule out diagonal attacks entirely once they know where the advisors and elephants are.
Why so few pieces use it
The two diagonal movers are also the two purely defensive pieces, confined to their own palace or their own half of the board. Diagonal movement in xiangqi is associated with short-range, static defence rather than the long-range attacking power the orthogonal pieces provide.
Related questions
Does the horse's move count as diagonal?
Not in the usual sense; it is one orthogonal step followed by one diagonal step, a combined move rather than a purely diagonal one.
Is there any piece that can choose between diagonal and orthogonal on the same move?
No. Every piece's directions are fixed by type; only the horse combines the two, and it does so in every move rather than by choice.
