Can the general help defend a soldier in xiangqi?
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
No. The general defends only the palace points orthogonally next to it, and your own soldiers can never get there: they start outside your palace and only ever move forward, or sideways once across the river. A soldier inside your palace is always an enemy one, and your general may capture it only if it is undefended.
Why the question comes up
Most discussions of a soldier reaching a palace are about the enemy palace, where the defending general is the one doing the capturing. On your own side, the pieces your general can actually help defend are the ones that can stand next to it: advisors, an elephant on the palace front-centre point, and any chariot, horse or cannon that comes back into the palace.
The limit worth remembering
The general only defends points inside its own palace, and only the ones directly adjacent to it, at most four and usually fewer. It cannot reach out to defend a piece standing even one point further away.
Related questions
Does the general defend an advisor next to it?
Yes. An advisor orthogonally next to the general is defended by it, as long as recapturing would not leave the general in check.
Is a general-defended piece ever unsafe anyway?
Yes. If the capturing piece is itself defended, recapturing would leave the general in check, so the general cannot take back and the piece was never really defended.
